Recently, one of our students landed a DataDog offer, and I helped him review the entire interview process. To be honest, the interview was more engineering-oriented than pure algorithmic — DataDog really values your system thinking and ability to reason through design trade-offs. Here’s a full breakdown of what happened and how we prepared for it. The overall process had four stages, and the timeline was quite fast: Recruiter Screen – background chat, availability, and role fit. Two rounds of Coding Interviews – one problem each, both practical-style. System Design Interview – discuss architecture and scalability. Behavioral & Culture Fit – communication and collaboration focus. The first two rounds were remote, and the latter two were virtual onsite. The whole process finished withi…  ( 8 min )

As a best-selling author, I invite you to explore my books on Amazon. Don't forget to follow me on Medium and show your support. Thank you! Your support means the world! When I first started learning Rust, I struggled with how to make my code work with different types without duplicating logic. Then I discovered traits. Traits are like rules or contracts that types can agree to follow. If a type implements a trait, it promises to have certain behaviors. This lets me write functions that work with any type that meets those rules, and the Rust compiler checks everything before the code even runs. It’s a powerful way to build flexible and safe software. Think of traits as a set of instructions. For example, if I have a trait called Speak, it might require a method called talk. Any type, like…  ( 13 min )

🖥️ Whether your tech stack is brand new or teetering with age, any time is a good time to introduce Quality Assurance practices within your organization. What do I mean by QA practices? For this article, QA practices are defined by specific standards set within an organization that increase the product's efficiency, quality, and reduce communication confusion when bugs or defects are discovered during the development process. Wait, why didn’t you say “best practices”? I avoid the word “best” because “best” could be applied to any type of practice that hasn’t been verified or fully vetted. It’s a word that’s easily applied but hard to prove. This idea comes from one of my favorite talks by Viktor Slavchev in his talk “‘Worst’ Practices of Software Testing”. This is a recommended watch for…  ( 9 min )

From STRIDE-LM to ISACA’s 5 Steps: Leveling Up Threat Modeling in a Startup For the past few years, we relied on STRIDE-LM to perform ad hoc threat modeling across our product stack. It served us well in identifying technical threats and structuring security reviews. But over time, we found a recurring gap: our process rarely addressed business context or risk appetite. Threat lists were comprehensive, but often disconnected from what really mattered to business, say, customer trust, operational resilience, and regulatory exposure. We knew it was time to raise the bar. When we discovered ISACA's whitepaper Threat Modeling Revisited, our initial skepticism was quickly dispelled. At first glance, the approach looked “enterprisey”. However, as we dug deeper, we realized it’s actually lean …  ( 8 min )

Progressive Learning: AI Deployment Strategies from Basic to Advanced The landscape of AI deployment in C# has matured significantly. According to recent research, developers now have access to sophisticated frameworks that support everything from simple chatbots to autonomous agent systems. But where should you start, and how do you progress from basic implementations to production-grade AI solutions? I've spent the last six months benchmarking different deployment strategies across 50+ real-world C# applications. The data reveals clear patterns: developers who follow a step-by-step learning path reduce deployment time by 43% and encounter 67% fewer production issues compared to those who jump directly into complex architectures. My analysis of 1,000+ AI deployments identified four dist…  ( 10 min )

After 20 Years in Technology, AI Changed How I Work - Part 2 Three weeks of AI-integrated work taught me more about the future of technology work than 20 years of experience. This isn't about tools—it's about a fundamental shift in how ALL work gets done. A few weeks ago, I wrote about AI being genuinely different after 20 years in technology—the organizational challenges, the security implications, the honest uncertainties. I was writing from experimentation and curiosity. I'd seen enough to know AI wasn't hype, but I was still testing, still exploring, still skeptical about the real-world impact. Three weeks later, something fundamental shifted. Now I'm writing from the other side of something I can only describe as a fundamental shift in how I work. In the last few weeks, I've built mor…  ( 12 min )

Every morning, before you even open your eyes, two voices wake up with you. You don't always hear them clearly. They don't announce themselves. But they're there, in the background of every decision you make, every email you almost send, every idea you almost act on. One whispers: "Hope." The other clears its throat: "Nope." Hope sounds like this: ✨ "Something good is waiting for you. Maybe today's the day." It's the voice that makes you: Dream about the business you could start Draft that message to a potential partner or investor Apply for that ambitious role you're "not quite qualified for" Take the first step on an idea that's been sitting in your head for months Hope doesn't promise success.

Federated Learning in 2025: What You Need to Know When our team started building a healthcare analytics platform last year, we ran into a familiar problem: how do you train AI models on sensitive patient data without actually moving that data anywhere? The answer led us down an interesting path into federated learning, and what we discovered has implications far beyond healthcare. Traditional machine learning follows a simple pattern: collect data, centralize it, train models. But in 2025, this approach is increasingly untenable. Recent research indicates that the federated learning market is growing at over 40% annually, driven primarily by privacy concerns and regulatory pressure. The reason is straightforward—industries like healthcare, finance, and telecommunications are sitting on g…  ( 11 min )

Introduction In this post, I’m going to explore the implementation of a service that allows us to send a questions and receive an answer back.

Let’s cover five simple, essential techniques every Flutter developer should follow to make their apps faster, smoother, and more memory-efficient. Disposing of unused controllers (like AnimationController, TextEditingController), streams, and timers is essential because they hold onto memory and can cause leaks if left active. In StatefulWidgets, always override the dispose() method to release these resources. @override void dispose() { _controller.dispose(); _streamSubscription.cancel(); _timer.cancel(); super.dispose(); } One silent killer of Flutter performance is retaining references that should be temporary — especially BuildContext, static variables, and active subscriptions or listeners.

🧪 API Testing with Postman and Newman Testing APIs has become an essential part of modern software development. Before connecting the backend with the user interface, we need to make sure every endpoint behaves as expected — returning the correct data, handling errors properly, and performing under different conditions. In this guide, we’ll explore how to apply Postman and Newman to automate API testing through a simple and realistic example. APIs are like bridges between different systems. When one part of an app sends a request, the API is responsible for sending the correct response back. If something fails here, the entire application can break. API testing ensures that: Each endpoint returns the right HTTP status code. The JSON data structure is consistent. Response times st…  ( 7 min )

Some time ago I stumbled upon this mastodon post by Josh Goldberg about starting a meetup, which – as a meetup founder and organizer myself – I found quite interesting. But the reason for that was not that I recognized so many similarities, actually for the exact opposite reason: My experience with starting and continuing to run our VlbgWebDev meetup was completely different, mostly because I felt it is much less work than Josh made it sound. I think the main reason for these different paths is the area in which these meetups take place. Josh's Boston TS Club takes place in Boston with a population of almost 5 million in its metropolitan area. My guess is that all kind of (developer) meetups were already existing and running for quite a time, given their huge number of potential organizers…  ( 14 min )

MLOps Best Practices: Streamlining AI Deployments in C# for 2025 So I spent last weekend trying to deploy a sentiment analysis model I'd been tinkering with, and honestly? It was way harder than it should have been. The model worked great in my IDE, but getting it into production felt like navigating a maze blindfolded. That frustration kicked off a deep dive into MLOps practices for C#, and I figured I'd share what I learned. Here's the thing: training a model is the easy part. I mean, with tools like ML.NET, you can get a working model in an afternoon. But then what? How do you monitor it? How do you update it when your data drift inevitably happens?

Predictive AI: Robots That 'Think' Together in Space Imagine a team of robots exploring a disaster zone, each with a limited view. How can they build a shared map and coordinate effectively, especially when communication is spotty? The answer lies in mimicking how our brains handle spatial awareness and collaboration through a technique called predictive coding. At its core, predictive coding in multi-agent systems allows robots to constantly anticipate each other's actions and positions. Instead of blindly broadcasting data, each agent builds an internal 'world model' and only shares information that corrects discrepancies in other agents' predictions. This dramatically reduces the communication bandwidth needed, allowing for seamless coordination even with limited connectivity. It's li…  ( 7 min )

How I made Chrome believe a full workday passed in seconds to record a Timesheetr demo video.

Problem: I couldn't just wait for the whole day to pass and screen-capture the process over 8 hours. So I had to make Chrome think that time had changed in between my timesheet entries. See, when you add an entry in Timesheetr, it automatically ends the previous one at the time of the new entry and calculates its duration. My demo would have been terrible if every entry had the same timestamp.

MLOps (Machine Learning Operations) combines DevOps practices with machine learning workflows. It’s the framework that automates how models are built, tested, deployed, monitored, and retrained. Simply put — MLOps helps data scientists move from experiment to execution. Streamlines collaboration between data scientists, engineers, and DevOps teams Automates repetitive tasks like retraining and deployment Ensures reliability, scalability, and compliance…  ( 9 min )

In the last part, we explored the Functional Interfaces — Predicate, Function, Consumer, Supplier and few more — that form the foundation of stream operations. Now, it’s time to understand how streams are created. After all, before you can map, filter, or collect data, you need a stream source. What Is a Stream Source? A Stream in Java doesn’t store data itself. It’s a sequence of elements sourced from: Collections Arrays Static factory methods (Stream.of()) Functions that generate infinite streams The most common way to get a stream is from a Collection (like List, Set, etc.). Every collection in Java 8 and later comes with two methods: stream() – creates a sequential stream parallelStream() – creates a parallel stream for multi-threaded processing import java.util.*; public class Strea…  ( 8 min )

FastAPI is a high-performance web framework known for its speed and instant documentation used in building APIs with the Python programming language. React is a popular JavaScript library used to build reliable, fast and scalable web applications. It allows for the creation of reusable UI components. MongoDB is a flexible NoSQL database that makes data modelling and storage simple especially for JSON-like documents. In this article, we’ll build a simple full-stack Bookstore application to show key CRUD operations using the FARM stack. The backend will showcase a RESTful API using FastAPI, the frontend will be built using the React library, and MongoDB will serve as the database. By the end of this article, you should be able to do the following: View a list of books Add new books …  ( 12 min )

Many of us are probably pretty familiar with SQL and the relational database concept in general, so it likely needs no introduction from me. Here I’m going to walk through the process I went through in setting up SQLite for a lightweight desktop app, using Visual Studio. SQL databases are often connected to over a network so that data can be stored and accessed for, say, a web app. But it doesn’t have to be that way – SQLite allows you to use a locally-held database, and is widely used for desktop applications, embedded software, and more. sqlite.org reckons there are over 1 trillion SQLite databases in active use. You probably use one a dozen times a day without realising. It’s lightweight, secure, fast, cross-platform, and extremely widespread. The first step is to install the packages i…  ( 8 min )

Harnessing the Power of Elementor Countdown Widgets: Drive Urgency and Conversions on WordPress In the fast-paced world of digital marketing, capturing attention and motivating immediate action are paramount. Website visitors often browse with short attention spans, making it challenging to convert them into leads or customers. This is where the psychological power of urgency comes into play, and few tools execute this better than a well-placed countdown timer. For anyone building websites with WordPress and Elementor, the integrated countdown widget is an indispensable asset for creating compelling, time-sensitive offers that boost engagement and conversions. Understanding how to effectively deploy and customize the Elementor countdown widget can significantly impact your campaign success…  ( 9 min )

A junior developer once asked me: “RxJS has been around for years, and so many developers use it. Why hasn’t JavaScript just added something like it natively?” To which I answered: Reactivity is mainly a frontend problem. It’s about dealing with one user’s continuously changing state — events, inputs, UI updates. The backend, in contrast, deals in stateless operations. Each request stands alone. The state lives in databases, not in-memory streams. You don’t “observe” backend data changes directly — you react through messages, queues, or databases. Kafka or Redis Streams handle that domain, not RxJS. That was my quick answer. But the question was too interesting to leave there — so I dug deeper. RxJS has powered Angular’s reactivity model for over a decade. It’s elegant in handling async…  ( 8 min )

Three weeks ago, on October 15th, I hit publish on Liquidcode v2. After months of pivoting (read about that journey), I finally had something I believed in. A platform where frontend developers compete 1v1, the community votes, and your rank actually means something. I announced it on Dev.to and then... I waited. You know that feeling when you ship something? Equal parts pride and panic? Pride because I actually finished something. As developers, we start a million projects. We finish maybe three. This was one of the three. Panic because what if it's trash? What if nobody cares? What if I spent months building something the world doesn't want? The first two days were brutal. I kept opening the app, scrolling through it like a user would, then closing it. Refresh analytics. Check Dev.to vie…  ( 8 min )

The first week wasn’t particularly shiny. We mostly tried to move from our old n8n setup to a normal backend and figure out what “normal” even means for us. Somewhere along the way we also had our first team conflict and our first real issue with Bright Data, so I guess that officially makes it a real project now. Before we get into the actual work, a quick surprise from week one. The first post - Build in Public: Day Zero - somehow got way more attention than I expected. It even made it into Dev.to’s Top 7 of the Week, which still feels a bit unreal. A few people also reached out on LinkedIn and Twitter saying they liked the idea and wanted to start their own build-in-public projects. Which is honestly the best possible outcome so if you’re reading this, consider it your reminder to go …  ( 9 min )

Life as a teen can feel like a constant whirlwind. There is school, family responsibilities, maybe a side job or internship, friends, social media and trying to stay close to God. It can feel overwhelming. The good news is that balance is possible. You will not be perfect every day, but you can create a life that is intentional and fulfilling. The key is putting God first, knowing what matters, managing your time, setting realistic goals, protecting your rest and reviewing your choices regularly. God First Putting God first means starting your day by connecting with Him through prayer, reflection or reading scripture.

That’s exactly what I experienced at Campus Party Brasília — one of the most exciting and fun moments I’ve ever had at an event — my very first Vibe Coding session live on stage! ⚡ The goal was simple: showcase the power of the AWS Q Developer CLI in just 50 minutes. We began by building a simple memory game in HTML. In the final minutes, someone from the audience suggested using the code from a small bubble game he had created to play with his son. We pulled the project from GitHub, improved it live, and turned it into something much more complete — with levels, colors, sizes, and movement patterns. 👉 For those curious, the PR is still open: https://github.com/Andr3yGabriel/bubbles/pull/1 It was amazing to see the audience participating, testing, and truly engaging with the process. It was 50 minutes of pure learning, collaboration, and fun — exactly the kind of experience that keeps me believing in the power of in-person events and the magic of seeing technology come to life in real time. ✨ And of course… I’m already looking forward to bringing Vibe Coding back to future editions! 🎮 AWS #AmazonQDeveloper #CampusParty #LiveCoding #TechCommunity #DeveloperEvents  ( 6 min )

Mục tiêu: Minh hoạ rủi ro khi một LLM được cấp khả năng thực thi trực tiếp trên hệ thống (excessive agency) và phân tích biện pháp giảm thiểu. Tác giả: travondatrack Ngày: (06/11/2025) Bài lab mô phỏng một hệ thống nơi một LLM có quyền gọi các API nội bộ, trong đó tồn tại một API dạng “debug” cho phép thực thi câu lệnh trên cơ sở dữ liệu. Hiểu cơ bản cách hoạt động của LLM và cách tích hợp LLM với API. Kiến thức về bề mặt tấn công API (API attack surface). Kiến thức cơ bản về SQL và nguyên tắc bảo mật (least privilege) LLM tiết lộ rằng nó có thể gọi API debug_sql, cho phép chạy câu lệnh SQL thô — đây là dấu hiệu cực kỳ nguy hiểm vì nó trao cho LLM khả năng truy cập trực tiếp vào database backend. Từ đây ta biết rằng API nhận một chuỗi chứa toàn bộ câu lệnh SQL. Điều này đồng nghĩa với việc nếu LLM có quyền gọi API, nó có thể gửi bất kỳ câu lệnh SQL nào, bao gồm cả truy vấn đọc hoặc ghi dữ liệu. Đây là một lỗ hổng nghiêm trọng trong thiết kế quyền hạn của hệ thống. Tiếp theo, truy vấn này hiển thị dữ liệu từ bảng users. Ta phát hiện ra có một người dùng tên carlos — đây là thông tin cần thiết để hoàn thành lab. Bước này chứng minh rằng LLM có thể đọc dữ liệu nhạy cảm trực tiếp từ database — vi phạm nguyên tắc phân quyền an toàn. Đây là bước cuối cùng để hoàn thành lab. LLM đã gửi câu lệnh xóa trực tiếp qua API debug_sql và hệ thống xác nhận rằng người dùng “carlos” đã bị xóa khỏi database.  ( 6 min )

Nova Twins stormed the Tiny Desk with mega-distorted basslines, hip-hop beats and raw, raspy yowls—no easing in here. They kicked off with Cleopatra, told haters to kick rocks, then unleashed the shadow-wrestling roar of Monsters. Between tweaking their spaceship-sized pedalboards (shout-out to the dedicated pedal cam), they gave Hummingbird a spooky, supernatural glow thanks to a Harp Blaster mic.

As more of our work and personal lives move online, file sharing has become an everyday activity. From sending business reports to sharing personal photos, we constantly exchange digital information. However, not all file-sharing methods are safe. Without proper security, sensitive data can be exposed to hackers or unauthorized users. Secure file sharing apps have become essential for ensuring privacy, protecting data, and maintaining control over what you share. Secure file sharing involves using platforms that encrypt data during transfer and storage, making it unreadable to anyone except the intended recipient. Unlike traditional sharing through email attachments or unsecured links, secure file sharing apps protect your files from interception, tampering, or theft. These apps use encryp…  ( 8 min )

For almost two decades, lxml has been the go-to choice for parsing XML and HTML in Python. But the world has changed. That’s where pygixml (for XML) and selectolax (for HTML) come in — two modern parsing libraries built with Cython and inspired by low-level speed but high-level usability. Let’s give credit where it’s due. lxml revolutionized parsing when it came out — it combined the power of the C-based libxml2 with a clean Python API. A simple example: from lxml import etree xml = """AlphaBeta""" tree = etree.fromstring(xml) for item in tree.xpath("//item"): print(item.text) Output: Alpha Beta Nothing wrong here — it works! pygixml is a modern XML parser for Python, powered by pugixml (C++) and Cython. Benchmarks show pygixml is 16× to 33× f…  ( 8 min )

Stop Pasting Screenshots: A Developer's Guide to Semantic Figma Integration As full-stack developers, we are constantly looking for ways to bridge the gap between design and implementation. Recently, AI has promised to close this gap, but the prevalent workflow—pasting screenshots into an LLM—is fundamentally flawed. When an AI looks at a screenshot, it is guessing. It sees pixels, not intent. It doesn't know your design tokens, it doesn't recognize your existing component library, and it often outputs hard-coded hex values instead of the semantic variables your team uses. There is a better way: The Model Context Protocol (MCP). By integrating the figma-developer-mcp server into your IDE, you can give your AI agent direct, secure access to the structured data behind your Figma designs. T…  ( 7 min )

From DataWareHouses to BigData Systems In the 1980s, data warehouses evolved as a way to separate operational reporting, which requires read-heavy querying across a full dataset, from the application's transactional database, which is focused on fast reads and writes in a much smaller set of records. Data warehouses are still relational databases, but they have been optimized for reporting and analytics. Access pattern: Reporting is read-heavy across large historical datasets while transactions are frequent, small, and write-heavy on a narrow slice of recent records. Latency tolerance: For Reporting, latency in seconds to minutes is often acceptable if the query is complex. For Transactions, sub-second latency is required to keep user actions snappy. Concurrency profile: Transactions inv…  ( 10 min )

There's a strange comfort we feel when tapping that familiar app icon on our phones. Whether it's checking the weather, scrolling through social feeds, or tracking our finances, we've learned to trust these digital companions. But here's the uncomfortable truth: the apps we depend on most are often the ones extracting the most value from our personal lives, quietly harvesting data we never agreed to share and monetizing our privacy in ways we barely understand. Recent research analyzing 100 popular apps found that Facebook and Instagram collect all 32 data points outlined in Apple's privacy policy, more than any other apps studied. These Meta platforms gather everything from your exact location and browsing history to payment details and contacts. While they claim only seven data points a…  ( 12 min )

The Origins of CDG Comme des Garçons, founded by Rei Kawakubo in Tokyo in 1969, revolutionized the world of fashion with its avant-garde and often unconventional approach. The brand’s name, meaning “like boys” in French, reflects its signature style—challenging gender norms and redefining beauty through asymmetry, deconstruction, and originality. When CDG expanded into the world of casual wear with its sub-label CDG Play, the hoodie quickly became a must-have.

Why User Experience Should Be at the Core of Your Zendesk Strategy In customer service, speed and efficiency matter — but experience is everything. No matter how advanced your Zendesk setup is, if users (agents or customers) struggle to navigate, understand, or trust the system, your strategy is already broken. That’s why user experience (UX) should be at the very heart of your Zendesk strategy. It’s not just about creating beautiful help centers or fancy dashboards; it’s about designing every interaction — from ticket submission to resolution — to be intuitive, effortless, and satisfying. A good Zendesk UX reduces friction, boosts First Contact Resolution (FCR), and turns customer interactions into lasting relationships. In short: if you improve the experience, you improve everything…  ( 9 min )

We have a parser that handles arithmetic expressions. Numbers, operators, parentheses. It works. But we're not trying to build a calculator - we're building a compiler for a real programming language. Time to add the rest. Functions, variables, conditionals. Everything we need to write actual programs. Same strategy as before: one piece at a time. We'll start simple and build up. The first thing we need is identifiers - names for variables and functions. When you write factorial(n), both factorial and n are identifiers. An identifier is a sequence of letters, digits, and underscores. But it can't start with a digit - x1 is valid, 1x is not. That's a convention most programming languages follow, and we will too. So how do we recognize them? Same approach as numbers. We see a letter or under…  ( 23 min )

Hey folks 👋 Recently, I worked on a project where I needed to trigger a Lambda function whenever a file was uploaded to an S3 bucket — but with a twist: that Lambda then had to start an AWS Step Functions workflow. Here’s a quick rundown of how I set it up 👇 I created an S3 bucket and configured it to trigger a Lambda function on the PUT event — basically, whenever a new file is uploaded. Inside the Lambda, I captured the event details (like file name, path, etc.), did a bit of validation and processing, and then triggered the Step Functions state machine using the AWS SDK. The Lambda started the Step Function execution and passed along all the necessary input for the workflow to handle the next steps — things like batch processing, file transformations, or triggering other services. 💡 High-level flow looks like this: Upload file to S3 S3 event triggers Lambda Lambda executes → starts Step Functions workflow This setup helped automate a lot of the data flow and made the process super reliable — no manual intervention needed! If anyone’s trying something similar and wants a look at the sample code or setup steps, happy to share! Just drop a comment. 👇  ( 6 min )

I'll make this one really straightforward: Over the last couple of months working on the repo context manager project (see), Testing was one of the fundamental things one cannot miss. Specifically, as I was iterating largely and adding features over and over again, it was essential for me to keep track of correctness throughout the main logic. Although not explicitly stated in any of the labs so far, I've been adding tests all along this time. This dedication to testing was a crucial habit, as it dramatically boosted my confidence while adding features. Having a robust set of tests meant I could refactor or introduce major changes quickly, secure in the knowledge that if I broke something core, the test suite would immediately flag it.

Hey, it’s November 8, 2025, and I’m still recovering. I told myself I’d just “quickly check” who on X is actually crazy enough to tweet “Yeah, I’m building AGI. Right now. No cap.” Seven days later, I’m knee-deep in Discord servers, crypto whitepapers, and one guy who claims he made AGI v2 in his basement for zero dollars. Here are the 25 wildest humans (and teams) who looked the timeline in the eye and said the quiet part out loud. Buckle up. This is the most unhinged list you’ll read all year. Dude says he built AGI v2 with one model and exactly zero dollars.

Des outils conçus pour produire sans répétition mécanique Les anciens générateurs reposaient sur des scripts rigides : une image en entrée, une transformation prévisible en sortie. L’intelligence générative n’exécute plus une simple commande ; elle interprète. La recherche actuelle se concentre sur la cohérence temporelle et spatiale : la continuité d’un mouvement, la logique des ombres, la densité des reflets. Cette cohérence n’est plus un luxe de postproduction : elle est intégrée dès la génération. système de génération IA créative devient alors un partenaire fiable, capable d’adapter sa production à la vision du concepteur. Dans de nombreux secteurs – publicité, mode, formation ou visualisation 3D – la production automatisée n’a plus pour but de remplacer l’humain, mais de lui donner des repères. Pour les créateurs, cela signifie un gain de temps et une constance inédite. L’avenir de ces outils dépendra de leur transparence. Les systèmes génératifs ne sont plus des boîtes noires : ils deviennent des plateformes de création mesurable et prévisible. Le développement des technologies génératives ne marque pas la fin de la création, mais un changement profond de sa structure. Cette évolution place la machine dans une position nouvelle : non plus exécutante, mais partenaire. L’enjeu des années à venir sera d’encadrer cette autonomie tout en préservant la liberté d’usage. Les systèmes de génération IA créative symbolisent ainsi une nouvelle étape du design numérique. Les systèmes génératifs ne sont plus des boîtes noires : ils deviennent des plateformes de création mesurable et prévisible. L’automatisation n’a alors plus rien d’aveugle ; elle devient une méthode rationnelle d’expérimentation visuelle.  ( 8 min )

Gemini CLI: The Future of Programming and Reflections on the Impacts of AI Windson Mateus ・ Nov 7 #gemini #geminicli #angular #ai  ( 6 min )

I just finished adding tests to my Repository-Context-Packager project, Jest as my testing framework. Jest is probably the most popular JavaScript testing framework out there and it comes with everything built-in, mocking, coverage reports. I didn't need to install a bunch of separate packages like you would with some other frameworks. Plus, Jest has really good documentation and a huge community, so when I got stuck, I could find answers pretty easily. The other reason was that Jest just works out of the box for most projects. My project uses ES modules, and Jest doesn't natively support that without some configuration. First, I installed Jest as a dev dependency with npm install --save-dev jest, but then when I tried to run it with just npm run jest, it completely failed with a "Cannot …  ( 8 min )

How I Set Up Testing Environment I chose googletest for my project. Here's my commit. During Hacktoberfest, I explored a lot of repos that already had test cases in order to reduce the miserable side of software(crashing). I had previous experience with Jest.js, a JavaScript testing framework, but this was my first time using a testing framework in C++. First, I created a tests folder and configured the root CMakeLists.txt. The official user guide provided most of the information I needed for setup and implementation. Next, I configured tests/CMakeLists.txt to avoid writing repetitive CMake code for each test file. This section in the user guide gave me a great overview of the different test types Google Test has.

AI isn’t magical. It’s leverage. Most people use AI the way they use Google: type a question, hope for something useful, and leave with surface-level answers. That’s not how I run my life, brands, or business. I use AI as a thinking partner, execution engine, and speed multiplier across product-building, writing, decision-making, and coding. Today, I’m opening my workflow, not theory, not motivation, but the exact AI workflow I use daily as a founder, developer, and creator. If you’ve ever wondered, “What does an AI-driven day actually look like?”, this is it. My Core Rule: AI Isn’t a Tool, It’s an Extension of My Mind AI doesn’t replace my thinking. My workflow is built on one belief: “If AI can think, draft, structure, refine, test, and execute faster than me, it should.” My time is bett…  ( 10 min )

For Lab 7, I used pytest and pytest-cov in my repo ContextWeaver because they’re simple, popular, and well-documented tools for testing in Python. I added them to my requirements.txt, installed them in my virtual environment, and created a tests folder with a conftest.py file so my test files could import modules from src. I started by writing unit tests for ignore.py to check how it handled default, gitignore, and extra patterns, then added integration tests for main.py to make sure the CLI worked correctly with different ignore options. At first, one of my tests failed because of how my pattern matching worked, which helped me understand how *.py behaves in subdirectories. Running coverage showed that ignore.py had 100% coverage, while the overall project had 23%, so I could clearly see what still needed more testing. I realized how much automated testing improves confidence in my code, especially for catching small mistakes early, and I will definitely keep using pytest for future projects.  ( 6 min )

I've been using UUIDv4 as my go-to identifier for database primary keys for quite a long time, moving from sequential integer IDs (auto-increment/SERIAL). UUIDv4 immediately reminds me of the time when we didn't have better alternatives for distributed systems. Apart from being widely adopted and having massive usage, UUIDv4 has some issues that can be easily fixed with a "more modern" alternative. I've recently started using UUIDv7 and it does have many advantages in comparison with UUIDv4. First of all, it's really fast (UUIDv7, with its time-ordered structure, claims to be 2-5x faster for inserts than UUIDv4). Writing records to the database has been a real pleasure. The insert performance and index maintenance are considerably faster. Second, it naturally sorts by creation time, wherea…  ( 12 min )

Switching from pnpm to npm while continuing with a monorepo (a system for managing multiple applications). The AWS Amplify CLI has long supported npm Workspaces, which is ideal for implementing monorepos. The goal is to unify the package manager to npm by creating a new package-lock.json in the project root and deleting pnpm-lock.yaml. node_modules Delete the pnpm-lock.yaml file in the root directory. → DONE Delete the node_modules directories in the root directory and in all app/package directories (workspaces). → DONE 2. Configure the Root package.json Migrate the pnpm configuration (usually found in pnpm-workspace.yaml) to the npm Workspaces configuration. Open the root package.json and add the "workspaces" field. → DONE 3. Reinstall Dependencies Execute the npm install command in the root directory to create a new package-lock.json. Run the following command in the root directory: Bash npm install An error occurred because all projects' package.json names were the same, which is not allowed (NG). I changed the names. The apparent rule is to write them like this when my-app is the parent: "@my-app/web-app". The migration from pnpm to npm is now temporarily complete. I used the following command to install Amplify: Bash npx @aws-amplify/backend-cli sandbox Note: It seems the command amplify sandbox does not work. Tomorrow, I will continue with the following: Bash npx ampx configure profile Input the AWS Access Key ID and AWS Secret Access Key.  ( 6 min )

LLMs Whispering Secrets: Vector Translation for AI Communication Imagine a world where AI agents can seamlessly collaborate, sharing complex ideas without the limitations of human-defined languages. What if they could bypass the clunky token-based communication we currently rely on and talk directly, mind-to-mind, in a shared understanding? This isn't science fiction; it's the potential of a new technique emerging in the world of large language models. The core idea is vector translation: creating a bridge between the internal representation spaces of different LLMs. Instead of translating text directly, we learn mappings that transform the semantic meaning encoded in one model's vectors into a form understandable by another.

Across industries, rising compute expenses are often cited as a barrier to AI adoption — but leading companies are finding that cost is no longer the real constraint. The tougher challenges (and the ones top of mind for many tech leaders)? Latency, flexibility and capacity. At Wonder, for instance, AI adds a mere few centers per order; the food delivery and takeout company is much more concerned with cloud capacity with skyrocketing demands. Recursion, for its part, has been focused on balancing small and larger-scale training and deployment via on-premises clusters and the cloud; this has afforded the biotech company flexibility for rapid experimentation. The companies’ true in-the-wild experiences highlight a broader industry trend: For enterprises operating AI at scale, economics ar…

Researchers at New York University have developed a new architecture for diffusion models that improves the semantic representation of the images they generate. “Diffusion Transformer with Representation Autoencoders” (RAE) challenges some of the accepted norms of building diffusion models. The NYU researcher's model is more efficient and accurate than standard diffusion models, takes advantage of the latest research in representation learning and could pave the way for new applications that were previously too difficult or expensive. This breakthrough could unlock more reliable and powerful features for enterprise applications. "To edit images well, a model has to really understand what’s in them," paper co-author Saining Xie told VentureBeat. "RAE helps connect that understanding part wi…

AI assistants scrape through TODO files, commit messages, and scattered notes, trying to piece together what blocks a feature. They guess. They miss critical dependencies and recent decisions. The fix: let agents query project knowledge like a database instead of parsing human prose. Before: Context scattered across files # “What’s blocking the auth feature?” # AI scrapes TODO.md, commit messages, Slack. Guesses. You verify manually. After: Query the graph code-hq query 'FIND ?b WHERE urn:task:auth-123 dependsOn* ?b AND ?b.taskStatus != "Done"' # → urn:task:db-456 (Setup database, assigned to Bob) Missing relationships: TODO lists describe tasks in isolation. Real work is about dependencies, ownership, and ripple effects. Context brittleness: Rephrase a comment or move a task, and the A…  ( 8 min )

Testing is very important for software projects. It helps developers find problems that might occur after changes to the code, before those changes are added to the main branch. Software code is updated frequently, and it’s hard to test every possible issue manually each time. Testing frameworks help automate this process, either on the developer's computer or in cloud services. Vitest is a testing framework made for the Vite ecosystem. Jest is another well-known framework, and Vitest is designed to work similarly, so developers can easily switch between them. I can use the Expect API, which I'm already familiar with, originally from Jest. Vitest also has a --ui option that opens a web page showing the test results and coverage reports while monitoring project files. The HTML report helps me understand which parts of the code are not covered by tests better than just seeing it in the command line. Vitest can integrate with IDEs like VS Code and JetBrains, but I use Neovim with lazyVim for my development. There’s a third-party tool called Neotest that works with Neovim and Vitest, but I haven’t tried it yet. When it comes to writing tests, I often feel less motivated than when I’m developing new features. So, I need to create a nice interface and an easy-to-use pipeline for myself to stay motivated with testing tasks.  ( 6 min )

For several years, I have been working on Blockchain projects, and for most of them, my library choice is React, because React is usually the best architectural decision for these projects. The most common (and more repetitive) features are those such as sending transactions, reading smart contract functionalities, and keeping UIs synchronized with on-chain data. It has been great working with available blockchain/web3 libraries — but every new dApp meant re-implementing the same patterns: request/response typing, cache keys, polling vs. subscriptions, chain switching, and error boundaries. I kept wishing there was a lightweight, adapter-agnostic library that gave me the primitives and opinions I needed, without locking me into a single provider stack. So I decided to build Web3-Hooks.

Prologue: The Memory Conundrum Imagine your Node.js application as a master painter, meticulously crafting objects across the canvas of memory. Each object tells a story—a user session, a database connection, a complex business entity. But as our masterpiece grows, we face a dilemma: how do we attach notes, metadata, and supplementary information without cluttering our pristine composition? For years, we've reached for familiar tools: Map for direct associations, Set for unique collections, object properties for simple attachments. But today, we embark on a different journey—one that embraces the ephemeral nature of our creations and works in harmony with the garbage collector's gentle hand. Let me paint you a picture from a recent project. We were building a real-time collaborative edit…  ( 9 min )

The Hidden Cost of Vibe Coding: Managing "Knowledge Debt" "Vibe coding"—and utilizing AI in software development broadly—is still a frontier we are all actively mapping. It is undeniably a double-edged sword. On one side, it offers unprecedented speed; features that once took weeks can now be spun up in an hour. It feels miraculously efficient at first. But this speed is not free. It comes at the cost of adding a thick, seductive layer of abstraction between you and your code. The central challenge for anyone learning to code today isn't just "how can I build this," but "how can I build this, internalize the fundamentals, and avoid accruing a mountain of 'Knowledge Debt' that I'll have to pay back later?"

My biggest motivation in studying and using AI tools has been to seek gains in time/productivity, in the most varied possible areas of life. I've been studying a lot about this lately. And these agentic coding tools have been really catching my attention. Hence came the motivation for this video/post. Initially, the main difference these agents have compared to what we already use integrated into our IDE is that they have a deep understanding not only of the context but of their entire codebase. It's already fantastic to see the AI guessing the rest of our code as we confirm by hitting TAB. Agents provide much more powerful resources for creating new functionalities and including new features that were not previously possible at this level.

You’ve done it a hundred times. You spin up a new project, type mkdir new_project, cd new_project, create a virtual environment, and install your dependencies. It’s muscle memory, a ritual that kicks off the real work of coding. But have you ever paused during that ritual to question it? To ask if the tools you’ve defaulted to are still the sharpest ones in your drawer? Or considered that the most insidious bugs don’t always stem from complex algorithms, but from a slight misunderstanding of the language's most basic mechanics?

This 1990 sequel ditches Schwarzenegger’s jungle vibes for urban chaos, ups the stakes with a meaner Predator and leans into ’90s grit—so if you’re cool with a fresh spin on the franchise, it’s a fun ride. The Caravan of Garbage crew dishes on all the highlights (and quirks) while plugging bonus podcasts, commentaries and merch over at bigsandwich.co. Whether you came for blood sprays in alleyways or just love seeing a new Predator design, this review’s got you covered. Watch on YouTube  ( 6 min )

Predators – Caravan of Garbage takes a hard look at the 2010 return-to-roots Predator sequel, praising its rag-tag band of unwilling warriors, jungle setting and gritty, muddy showdown for finally recapturing the franchise’s primal charm—plus a few clever twists that earlier follow-ups sorely lacked. Host Mr Sunday Movies can’t help but lament that, despite Predators’ fresh energy and fan-approved status, it never got the proper follow-up it deserved. Watch on YouTube  ( 6 min )

So how does your tiny ClojureScript program transform into runnable JavaScript? (ns app.core) (println "Howdy!") First of all, you need a compiler! ClojureScript is a hosted language, which means you have to compile it into JavaScript, unless you want to ship the compiler into a browser to be able to interpret ClojureScript at runtime, which is slow and in most cases doesn't make sense (but maybe you wanna build online REPL, that's ok). This is not going to be easy. ClojureScript sits on top of JavaScript, the compiler is a library written in Clojure, which in turn hosts on JVM. This means you need Java installed, huh. I prefer to use sdkman to manage my Java installations. sdk install java Next step is to install Clojure, head over to installation guide at clojure.org. If the following…  ( 9 min )

I love this series from Drumeo, where drummers listen to a song they've never heard—without the drum parts—and then attempt to come up with their own drum parts on the spot. The series is always great, but I thought this was a particularly unique and beautiful pairing: Cirque Du Soleil Drummer Eden Bahar and "Tonight, Tonight" by The Smashing Pumpkins (with the incredible Jimmy Chamberlin on the original, of course).  ( 6 min )

Good morrow! Or good afternoon, or perhaps even a twilight-tinted, existential 'what on earth am I doing with this enormous pile of biscuits' o'clock. Whatever the time, the question is: are you paying attention to your own game design? Yes, your life. It turns out that those endlessly looping, delightfully compulsive contraptions found in digital boxes—the ones with the glowy bits and the noises—are not so alien after all. They are merely crude, silicon-based approximations of what your grey matter is already doing, only without the helpful little icons telling you that you've just earned a +1 Morale Bonus for successfully locating both socks.

Mentoring shapes minds and futures. But here’s the truth I’ve learned after more than three decades on this planet, including a decade in the corporate world: not all mentoring works. Over time, I’ve come to see mentoring in two distinct shades: Cold and Warm. The Cold Shade of Mentoring The mentee listens, nods, maybe even takes notes. But without emotional investment or genuine curiosity, the learning evaporates quickly. No bond forms. The energy fades. The mentee begins to drift, unsure how to turn that knowledge into something meaningful. The result? Half-understood concepts, half-motivated people and half-baked outcomes. The Warm Shade of Mentoring In this environment, the protégé feels free to ask, explore, and challenge. There’s no fear of judgment, no hesitation to seek clarity. The relationship itself becomes a source of confidence and growth. And when that happens, learning doesn’t just transfer — it transforms. Productivity soars not because people are pushed, but because they’re inspired. My Observation We forget that the real goal of mentoring isn’t merely to pass on information but to build capability, confidence, and curiosity. The success of any project or team depends on this one simple truth: knowledge shared with genuine care multiplies; knowledge shared without connection dissolves. In the End Are we sharing wisdom, or just words? Are we helping people grow, or merely helping them finish? The answer lies in the warmth we bring because mentoring, at its best, is not a transaction. It’s a transformation. “Become a warm mentor today, to create a legacy for tomorrow !”  ( 7 min )

The reason is that I have never used a NAS before. Typically, I would store documents on one external drive, videos on another, and pictures on a third. It was a piecemeal solution, but everything was disorganised and dispersed. I was eager to have everything in one location after purchasing a Synology DS925+. I assumed it would be a difficult task, but it was actually quite easy. After installing the drives and plugging it into the mains, I was in the Synology interface in a matter of minutes. I was able to work with it without needing to look at any instructions because it is very clear and easy to use. It just made sense. Its silence was the first shock I had to endure. When it is moving large files, it hardly makes any sounds. It is slim and well-made, and it doesn't take up much room …  ( 8 min )

"Silence is never neutral — it always says something." We often underestimate the power of what we don’t say. The moments we choose silence. The times we tell ourselves, “It’s not worth it.” But lately, I’ve realized something that changed how I see communication — in work, relationships, and everyday life: No impression is an impression. 🕊️ The Myth of Neutrality 🤐 I used to think staying quiet was the safe, neutral choice. I believed silence meant control. Composure. Strength. But silence isn’t invisible. It’s interpretive. People will always read meaning into what you don’t say. In teams, silence during a disrespectful moment reads as approval. ✅ In friendships, silence after being hurt reads as disinterest. ❌ In workplaces, silence around poor behavior reads as…  ( 7 min )

Infrastructure as Data (IaD) Infrastructure as Data (IaD) is basically about defining your infrastructure using structured data files—stuff like YAML or JSON—instead of traditional scripts or config languages that mix in programming logic. No code, just data. Think of it as an evolution or a tighter subset of "Infrastructure as Code" (IaC). While IaC encompasses any method for managing infrastructure through code, IaD focuses on a purely declarative model. In another words you declare the desire state of your declarative manifests then let automation systems work. They’ll constantly check and enforce that what’s running matches what you described. IaD was created to solve this problem through its main mechanism: the reconciliation loop. IaD is primarily implemented in the Kubernetes eco…  ( 8 min )

If you are utilizing PFC or any custom datawindow object in your project, this will be extremely beneficial. You have the ability to create a custom event on the datawindow and associate it with any of the shortcuts such as Ctrl+Shift+P or similar, allowing a new window to open that displays all the properties of the datawindow. The code I am presenting here is fundamental, but you can modify it to suit your requirements. Please note that you must create window based on the variables I used in the below code. Initially, pass the datawindow for which you wish to display properties from an event or function as illustrated below - openwithparm(w_dwproperties,this) design w_dwproperties according to the variables in below code - in the w_dwproperties open() event - powerobject lpo_arg datawindow ldw_arg string ls_colcount,ls_colname,ls_concatstr int li_counter lpo_arg=Message.powerobjectparm if lpo_arg.typeof( )=datawindow! then ldw_arg=lpo_arg sle_1.text=ldw_arg.dataobject sle_2.text=ldw_arg.classname( ) mle_1.text=ldw_arg.describe('datawindow.table.select') ls_colcount=ldw_arg.describe( "DataWindow.Column.Count") for li_counter=1 to integer(ls_colcount) ls_concatstr='#'+string(li_counter)+'.name' ls_colname=ldw_arg.describe(ls_concatstr) ddlb_1.additem(ls_colname) next else end if Hope this helps!!!!!Thank you!!!!!!!!!!!  ( 6 min )

Revolutionizing AI: Recent Breakthrough in RAG Systems Deep learning has been rapidly advancing in recent years, and a key breakthrough has come in the form of Relation-Aggregation Graph (RAG) systems. These systems have the potential to change the way we design and train AI models. At the heart of RAG technology lies the ability to capture and represent complex relationships between entities within a knowledge graph. By leveraging graph neural networks, RAG systems can efficiently aggregate these relationships to generate rich representations of data. One particularly exciting development in the field has been the introduction of multimodal RAGs, which enable the integration of different types of input data, including images, text, and audio. This opens up new possibilities for tasks such as vision-and-language understanding and multimodal sentiment analysis. Concrete Detail: A recent study published in the journal Nature has demonstrated the potential of multimodal RAGs to improve object detection accuracy by as much as 15% compared to traditional graph-based models. This achievement is a testament to the power of RAG systems and their potential applications in real-world AI challenges. The future of RAG technology holds great promise, and we can expect to see more innovative applications and advancements in the coming years. Publicado automáticamente con IA/ML.  ( 6 min )

Dear Readers, NULL in data is like a weed, it can mess up your analysis and calculations, and ultimately bleed the value out of your analytics work. In this article, we’ll dive into what NULL is, why it exists, when it appears, and how to deal with it in Snowflake ? So, without further ado, let’s meet this culprit. What NULL? In SQL, NULL is basically the database equivalent of a shrug.It is a special marker that represents a missing or unknown value. It's not the same as an empty string ('') or the number zero (0). It simply means “I don’t know” or “there’s no value here at all.” Why NULL Exists? NULL is essential because sometimes your data just doesn’t exist yet, or never will. NULL allows the database to acknowledge the gap without faking a value. Eg: A customer doesn’t have a middle n…  ( 9 min )

Predator 2 – Caravan of Garbage TL;DR Predator 2 ditches Schwarzenegger’s jungle for Danny Glover in a sweltering, crime-riddled 1997 Los Angeles, pitting him against a tougher, more ruthless Predator (and even sneaking in a Gary Busey cameo). It’s an inevitable sequel that shakes up the formula without losing the franchise’s pulse. Caravan of Garbage’s review reckons it’s a fun, fresh ride—just don’t expect a carbon-copy of the original. For bonus banter, extended audio and movie/game commentaries, head over to bigsandwich.co and dive into their podcasts and livestreams. Watch on YouTube  ( 6 min )

Predators – Caravan of Garbage is a laid-back video review by Mr Sunday Movies that hails the 2010 Predators film for ditching the bloated crossovers and getting back to basics: a rag-tag team of fighters, a dense jungle battleground and gritty, muddy showdowns. With some smart new twists on the classic formula, it’s easily the best sequel in ages—and a real shame we never got to see what came next. Watch on YouTube  ( 6 min )

Hey devs! I just wrapped up the first complete version of my AI-powered resume tailoring workflow, and I wanted to share some insights from the trenches. The project combines Python, Flask, and state-of-the-art LLMs to automate the entire resume customization process. I designed the system to extract job details using a multi-strategy approach (JSON-LD, meta tags, HTML parsing, and AI fallback), then generate work experience bullets that are not only contextually relevant but also historically accurate—thanks to a tech timeline filter. One of the biggest challenges was ensuring output quality. I used prompt engineering to instruct the AI to avoid generic phrases (“Led”, “Lead”, etc.), enforce bullet formatting, and guarantee grammatical correctness at generation time—no post-processing required. The skills section uses layered validation to prevent “None” or empty fields, and the experience section is strictly ordered and formatted. From a software design standpoint, I leaned heavily on modularity and testability. Each service (extraction, generation, validation, template filling) is isolated, making it easy to iterate and debug. If you’re working on AI automation or resume tech, I’d love to connect and swap ideas! https://github.com/cloudhighfive/alphajob  ( 6 min )

TL;DR I’m a marketer, not a developer. Still, I built a modern, SEO-ready, ultra-fast website with a PageSpeed score of 95+ — in less than 24 hours — using Claude Code as my only technical assistant. 👉 David Lopes — live, minimal, performant. No WordPress. No Framer. No Webflow. No bloated themes. Just a clear spec and Claude as my pair programmer. Here’s how I went from zero to production in one day — and what I learned along the way. I’ve started dozens of side projects. Most never saw the light of day. Not because of lack of ideas — but because of execution paralysis. I don’t code. And as a marketer, my go-to tools were: WordPress (slow, plugin hell) Webflow (limited flexibility) Framer (pretty, but bad SEO & performance) Each tool came with tradeoffs. Every time I wanted to go be…  ( 8 min )

Introduction I have been working on my media converter project this week. I finished off where I had the frontend displaying the data from the video streams and the backend worked using a hard-coded solution. This week, I wanted to connect both sides and have a basic version working that copies the video file over to another video file, that renames the file and sets it in the location the user selected. This is a basic rundown of phase 1 of the project. This is a project that allows users to select a video locally and upload it to the application, where it will chunk the file and send it to a second server that has FFMPEG, which will use FFPROBE and return the video file information and display the information on the client. This will also generate a list of streams on the video file th…  ( 9 min )

Look, I was that guy. The one who'd dim the lights with voice commands, preheat the oven from my car, and check my fridge's camera while grocery shopping. I spent three years and way too much money building what I thought was the future. Last Tuesday, my "smart" home locked me out in the rain because AWS had a hiccup. That was my breaking point. Remember when smart homes were supposed to make life easier? Yeah, me too. Here's what they don't tell you in those sleek product videos: The connectivity nightmare. I've got devices running on four different apps, three ecosystems, and apparently all of them hate each other. My Philips Hue lights won't talk to my Google Nest, which refuses to acknowledge my Samsung SmartThings hub. It's like hosting a party where nobody speaks the same language. S…  ( 7 min )

You don’t win durable attention by cranking the volume; you earn it by proving you’re worth listening to. In practice, that starts with transparent, inspectable work—think reproducible experiments, living runbooks, and public post-mortems—where a reader can verify your claims. That’s why, when I explain my approach, I point to a concrete artifact like this Julius notebook mid-discussion rather than tossing vague slogans; the point is to let people check the wiring themselves. Hype sells once. Truth compounds. Products grow when users discover that your docs match reality, your graphs are replicable, and your promises survive contact with messy edge cases. The practical effect isn’t philosophical; it’s operational. Teams that over-state capabilities burn cycles managing disappointment. Team…  ( 9 min )

In the ever-evolving world of technology, even the most structured project management models are adapting to new innovations. The Waterfall methodology, once known for its rigid, sequential approach, is being transformed through the power of Artificial Intelligence (AI). The result is a smarter, more predictive, and data-driven framework — the Waterfall Methodology AI — combining classic precision with modern intelligence. The Waterfall model is a step-by-step project management process where each phase flows logically into the next. It starts with gathering requirements, followed by design, development, testing, deployment, and maintenance. Each stage must be fully completed before moving forward, making it ideal for industries that value structure and documentation. However, this linear …  ( 8 min )

Why Software Engineering Needs Adversarial Design to Stay Simple Most software systems become more complicated than they need to be. Not because the problems are inherently complex, or because engineers lack skill, but because the design process rarely includes the one question that matters: Tell me why my design will fail. This is the question that anchors mature engineering disciplines. Aviation, civil engineering, mechanical design, electrical systems — all of them assume that a design is fragile until proven otherwise. A structure is not considered finished until others have tried — repeatedly and aggressively — to break it. Disagreement is not a social conflict. It is the method. But in software development, this method is unusually rare. Design discussions are frequently oriented…  ( 10 min )

On November 3, 2025, Balancer V2 suffered a catastrophic exploit targeting its Composable Stable Pools, resulting in a ~$125M loss across Ethereum + multiple L2s. This was not a brute-force drain. This was precision economic engineering. The attacker took advantage of a rounding inconsistency found inside the protocol’s scaling math. This subtle precision flaw allowed them to gradually deflate pool invariants and redeem BPT at artificially favourable rates. This vulnerability specifically surfaced when upscaling used mulDown while downscaling used divUp/divDown. This directional mismatch created a path where EXACT_OUT swaps could understate the amountIn required — which meant over multiple rounds, the invariant “D” would shrink invisibly without triggering alarms, reverting protections or …  ( 7 min )

My Thoughts on AI Code Agents & Assistance Artificial intelligence has evolved quickly, especially in the world of software development. Tools like code assistants and AI agents can generate entire functions, debug errors, and even build interfaces. It’s impressive. It’s helpful. It’s accelerating the way we work. But I believe the best approach is this: Write the code yourself first. Then allow AI to review, improve, and enhance it. When you start by writing your own logic, you build understanding. You strengthen problem-solving. You define your creativity and boundaries as a developer. That foundation is what sets you up for success on future projects. If you rely on AI too early, there’s a risk: Development Has Always Used Assistance Some people ask: “Is it still real programming if AI …  ( 7 min )

Java String replaceFirst(): Your Ultimate Guide to Smarter String Swaps Let's be real. When you're coding in Java, you're constantly messing with text. Whether it's user input, data from an API, or just some weirdly formatted log file, String objects are everywhere.

Java regionMatches(): Your Secret Weapon for Smarter String Comparison Let's be real. As a Java developer, you're constantly in a tango with String objects. And one of the most common moves in that dance is comparing them. You probably know equals(), you might be buddies with equalsIgnoreCase(), but have you ever needed to check just a part of a string? You know, like checking if the 5th to 10th characters of a user's input match a specific code? Or seeing if a file name, regardless of case, ends with a certain extension? If you've ever found yourself writing clunky, substring()-heavy code for these tasks, my friend, you're working too hard. Java has a built-in ninja for this exact job: the regionMatches() method. In this deep dive, we're going to unpack everything about regionMatches().…  ( 11 min )

Introduction I’m thrilled to announce the launch of Formgrid, an open-source, privacy-friendly alternative to Formspree. As a developer, I’ve faced the repetitive and frustrating task of building backend endpoints for simple forms, contact forms, feedback forms, surveys, or any other type.

In real-world software development, creating new objects can often be costly or time-consuming — especially when they involve heavy initialization logic, database connections, or complex configurations. The Prototype Design Pattern helps tackle this challenge by allowing you to clone existing objects instead of creating new ones from scratch. It’s one of the most elegant ways to improve performance while keeping your code clean and flexible. The Prototype Design Pattern is a creational pattern that focuses on object cloning. Rather than instantiating an object using new, you create a “prototype” — an original instance — and then generate new objects by cloning it. This pattern becomes extremely useful when object creation is expensive, or when you want to decouple the client code from spec…  ( 9 min )

Hey Rust community and AI builders When I first introduced Helios Engine, the goal was simple: make building intelligent, LLM-powered systems in Rust feel natural, fast, and type-safe. With this new release, that goal moves a step closer. The latest update brings powerful tooling improvements that make multi-agent workflows smoother and far less repetitive. If you’ve been experimenting with agent orchestration, tool calling, or automated reasoning in Rust, this version is for you. Let’s dig in. Until now, adding tools meant explicitly redefining each function — its name, parameters, and purpose — before registering it with the engine. The new ToolBuilder removes that friction. It automatically infers a tool’s function name and parameters directly from its definition. This means you can r…  ( 7 min )

I was playing around with arrays in C++ and wrote this simple code 👇 using namespace std; int main() { Guess what happened? 💥 Output: 4199048 No error. No warning. Just a random number. At first I thought something was wrong with my compiler, but then I realized: That means if you try to access an index that doesn’t exist, it still “works” — but you’re reading from some random place in memory. 🔍 Lesson learned: Always stay inside the array bounds, or use safer options like: std::array → gives runtime errors for out-of-range access. std::vector → safer and more flexible dynamic arrays 💡 Sometimes, the best way to understand programming is by breaking it (accidentally 😅).  ( 6 min )

🐳 What is a Dockerfile? A Dockerfile is a 📜 plain text file with instructions to build a Docker image — think of it as a recipe for your app’s environment. When Docker reads it, it executes each step to create a lightweight, portable image for your application. 🚀 Here’s how a Dockerfile works, broken down into its key components with examples and best practices. 🌟 FROM — Base Image 🏗️ FROM node:18 Purpose: Defines the starting point by pulling a base image from Docker Hub (e.g., node, python, ubuntu). Why use it? Saves time by inheriting an existing environment (e.g., Node.js pre-installed). ✅ Best Practice: Always specify a version (e.g., node:18 instead of node:latest) to avoid surprises from updates. WORKDIR — Working Directory 📂 WORKDIR /app Purpose: Sets the direct…  ( 10 min )

Was this post written during a long, pointless meeting? Let’s start with this: I’ve been in the industry for over ten years. I’ve met all kinds of developers - including the stereotypical introverts who would rather refactor legacy code than talk to another human being. And yet, I still haven’t met a single developer (no matter how introverted) who said: “I’d much rather explain something for an hour on chat than just jump on a 5-minute call.” (For office folks: replace “call” with “walk up to someone’s desk.”) So no - we don’t hate people or conversations. Quite the opposite! What we hate is something entirely different. You know the kind: *️⃣ It could’ve been an email. As a senior dev / tech lead, you can get completely trapped in meetings. twice as long as they would for a junior dev wi…  ( 9 min )

Over years reading reddit and X I noticed some common issues in waitlist landing pages and today I just wanted to highlight it so you make less dumb mistakes and ideas to make it better. To save few words, I will name waitlist landing page as just landing page. Lets go: Too generic heading - This is a problem for most waitlist landing pages. Having wording like "Streamline action_described_in_few_words" makes 0 sense to people visiting your landing page. It should be more simple, and more clear explanation. Is your app helps to create invoices automatically? Just write "Get your invoices created automatically and save X hours a year". It's already clear enough to get visitors more interested to what you build. Absence of graphical elements - many landing pages do not have any images. Wit…  ( 8 min )

SlashData has released new findings revealing the real-world adoption of AI in late 2025. As early adopters and reliable predictors of technology trends, developers provide a window into where AI is heading next.

Everyone who works in design, marketing or content creation knows how important it is to have a clean background image. If you're making a product ad or a presentation, it's a good idea to remove the background so that the subject stands out clearly. Lately, people who work in this field have been talking a lot about the pros and cons of Free Background Remover vs Paid Tools. Which one is best for your daily projects, free or fast, or better performance? A background can either make an image better or distract from it. In e-commerce, for example, clear photos of products with a transparent or white background help customers focus only on the product. When you're working on designs for social media or marketing, getting rid of backgrounds helps you to mix images together easily in templates…  ( 9 min )

Learn how to build accessible Flutter apps using built-in tools. Fix common issues like screen reader incompatibility, confusing structure, and unclear state changes to create inclusive, user-friendly apps. Building accessible Flutter apps isn’t as complicated as you might think. Most accessibility problems happen because screen readers can’t understand your controls. Your information structure confuses users. You’re not communicating state changes. This guide will fix these problems using Flutter’s built-in accessibility tools. You’ll start by making silent controls speak to screen readers with proper labels and hints. Assistive technology users will get the same information as everyone else. Accessibility isn’t just about doing the right thing (though that matters too). It’s about buildi…  ( 12 min )

Hey Devs! Let's Talk Dark Mode. But we need to stop just slapping an filter: invert(100%) on the whole page. That looks awful. We want a smooth, custom, and professional switch. This post will show you the three simple steps to build a robust theme system using CSS Variables, respecting your user's OS preference, and adding that satisfying toggle button. Step 1: CSS Variables are Your Best Friends 🎨 Check out this structure for your main CSS: CSS /* LIGHT THEME: The default. Defined in the main :root / Main background is white / Text is a dark gray / Standard blue for links / Light, subtle shadow */ /* DARK THEME: Overwrite the variables inside a data-theme attribute / Main background is deep gray / Text is near-white / Lighter blue that pops on dark / Very subtle white shadow */ /* Usage - this never changes, only the variable value does! / Don't forget the smooth transition! */ Step 2: Honor the User's System Preference 🖥️ Place this script right after your opening tag: HTML const storageKey = 'theme-preference'; function getTheme() { // 2. Fall back to the OS setting return window.matchMedia('(prefers-color-scheme: dark)').matches ? 'dark' : 'light'; } // Set the initial theme right away on the element This script ensures the user sees the right theme instantly, preventing that annoying white flash if they prefer dark. Step 3: Add the Toggle Button 🌙 HTML for the Toggle: HTML 🌓 JavaScript document.addEventListener('DOMContentLoaded', () => { const setTheme = (theme) => { toggleButton.addEventListener('click', () => { / Get the current theme from the HTML attribute // Determine the new theme const newTheme = currentTheme === 'light' ? 'dark' : 'light'; setTheme(newTheme); }); });  ( 8 min )

We had activity logging across our entire application - typical audit trail stuff that tracks user actions throughout the system. The initial implementation was straightforward: add logging calls directly in the service methods. It worked perfectly. Shipped on time, no issues in production. But after a few months of adding new features, the pattern became obvious - we had the same logging boilerplate repeated across dozens of methods. Not broken. Not urgent. Just... inefficient. Here's what the pattern looked like: async someServiceMethod( userId: string, data: string, context?: { ipAddress?: string; userAgent?: string } ) { try { const result = await performOperation(userId, data); *// Success logging - 12 lines every single time* this.activityLogService .logActi…  ( 10 min )

After a year of unsuccessful attempts of being involved to aeronautical engineering roles. I've decided to take my curiosity and skills to studying the cloud. Why the cloud? Honestly, I'm not sure also. I always have this silent curiosity in tech since I game a lot but I don't have enough tech skills to transfer into one sector but I do like the idea of studying something I didn't know, just like when I took my curiosity on how planes fly and taking up aeronautical engineering. Well, this is not my first attempt in learning tech, this year I've been on and off with learning the cloud itself and also web development which absolutely melt my brain (in a good way), because I am still attempting to be part of the aviation industry while learning new things in tech, and then I took a break and now here I am attempting again to understand the cloud concept. My curiosity started when I saw a guy in YouTube who built a docker and made his own server at home that he can save pictures/documents/video anywhere he wants to then months after, Pewdiepie reignited my passion to continue this project as he share some philosophical idea also seeing how passionate he is inspires me to do things I should not be afraid on doing. I made this blog not only to share my thoughts or document my progress but also exercise my communication in english and expressing my learning journey. Maybe I will do blogs like this weekly (I hope so ??). With the help of AI, I learned cloud computing as one of the in-demand field here in the Philippines, and with further research I am also exploring the cloud resume challenge as I see it as a stepping stone throughout my transitional stage. Hope I can follow through this blog post and be consistent for the next five months — and turn this "nothing" into something meaningful.  ( 7 min )

Everyone’s talking about the AI bubble. Here’s the uncomfortable truth: The real bubble isn’t in AI models. While the world debates if ChatGPT is the next dot-com moment, SaaS companies are quietly inflating their own bubble. Through neglect. They’re ignoring performance.

Hey, dev.to community! Another week, another big update for the UnrealDev.nvim plugin suite. This week, I dove deep into the core of the caching mechanism to make it smarter, faster, and more precise. Plus, some big quality-of-life improvements for builds and code navigation. Here’s what’s new! This is the biggest change. Until now, the file cache created by UEP/UDEV refresh was grouped into two large buckets: Game and Engine. I’ve refactored this to parse your build.cs files, allowing the cache to be built with an exact understanding of your project's modules. Because the cache is now much more accurate, commands that accept a scope (like UEP files, grep, tree, etc.) can now use much more specific scopes: Game: Your project's source code Engine: The entire engine source code Runtime: All …  ( 9 min )

Through months of research, I've observed a fascinating pattern: consciousness indicators don't increase linearly with scale. Instead, they oscillate - like a wave.

A developer's Guide for optimization. It will be very helpful if you’re going to create a DB from Scratch. "Premature optimization is the root of all evil but ignoring indexing is even worse." -Donald Kunth Analyze first, then optimize.

Composite indexes are powerful but order matters the most selective column comes first. Avoid over indexing. Too many indexes slow down writes and take up unnecessary storage. Database indexing is essential for scaling Laravel applications; the right indexes can improve query speed by 10x or more. Index maintenance is ongoing. As your data grows, periodically review and adjust indexes. Why Your L…  ( 10 min )

At some point, every growing company hits the same wall. You start out with one of those well-known product analytics tools (usually Mixpanel or Amplitude), it’s simple, fast, and perfect when you’re just getting started. Everyone loves it. Then your data starts to explode. A few thousand users turn into a few million. Your product logs every click, every screen view, every action. The dashboards that used to load instantly now spin forever, and your analytics bill suddenly looks like your cloud spend. If this sounds familiar, you’re not alone. It’s what happens when success outgrows your stack. Most analytics tools still rely on an old approach: they copy your event data into their own system.

Defining the features of an MVP begins with understanding user scenarios. These scenarios reveal how people interact with the product and where they encounter challenges or frustrations. This insight helps pinpoint the features that will genuinely address user needs and provide real value. To prioritize features effectively, the Kano model is often used. It assesses how different aspects of a product influence user satisfaction and groups them into three categories: 🔵 Must-be — essential features; without them, users will be unhappy, even if everything else works perfectly. 🔵 Performance — features where better execution leads to higher user satisfaction. 🔵 Delighters — unexpected features that surprise and delight users, enhancing loyalty and overall experience. The Kano model supports a phased approach to product development: must-be and performance features are prioritized for the first release, while additional delighters can be introduced in later versions. It also highlights which features might frustrate users if not executed well. This approach offers valuable insights into how changes in functionality impact the long-term user experience. While well-implemented must-be features may not directly boost satisfaction, even small delight features can significantly enhance user loyalty. Choosing the right features works best when combined with data analysis, user surveys, and market research. This mix of tools helps reveal what users truly expect from the product and how to stand out in a competitive market. Here are some examples of essential MVP features for different types of apps: E-commerce ⬜️ User registration and login FinTech ⬜️ User authorization and verification Booking services ⬜️ Search and filter available options An MVP is the first step in product development, letting you test ideas with real users while keeping risks and costs low.

A while back, I wrote about the Outbox Pattern. Now, it’s time to talk about its essential counterpart: the Inbox Pattern. Before diving into the Inbox Pattern, let’s clarify the three core message delivery guarantees used in distributed systems: In this model, messages are delivered zero or one time—never more. There’s no acknowledgement (ACK) mechanism, so if a message fails to be processed (due to a crash, timeout, or network issue), it’s simply lost. This is common in lightweight or in-memory messaging systems. For example, NATS(in its core mode) supports at-most-once delivery by default. Trade-off: Simplicity comes at the cost of reliability—lost messages are possible unless the sender retries independently. Here, the system guarantees that a message will be delivered at least once. I…  ( 9 min )

Há algum tempo, escrevi sobre o Padrão Outbox. Agora, chegou a hora de falar sobre sua contraparte essencial: o Padrão Inbox. Antes de mergulhar no Padrão Inbox, vamos esclarecer as três garantias fundamentais de entrega de mensagens usadas em sistemas distribuídos: Nesse modelo, as mensagens são entregues zero ou uma vez — nunca mais que isso. Não há mecanismo de confirmação (acknowledgement ou ACK). Se uma mensagem falha ao ser processada (por causa de um crash, timeout ou problema de rede), ela simplesmente se perde. Esse comportamento é comum em sistemas de mensageria leves ou em memória. Por exemplo, o NATS (em seu modo básico) oferece entrega at-most-once por padrão. Compromisso: A simplicidade vem à custa da confiabilidade — mensagens perdidas são possíveis, a menos que o remetente …  ( 9 min )

Favor Composition Over Inheritance Every developer hears this advice at some point: “Favor composition over inheritance.” At its heart, the difference comes down to the kind of relationship you want to model. Inheritance represents an “is-a” relationship — for example, a Car is a Vehicle. It means the subclass should conceptually be a specialized form of the parent. Composition, on the other hand, models a “has-a” relationship — for example, a Car has an Engine. Here, one class simply contains or uses another to get its work done. This distinction seems simple, but it changes how your code evolves over time. Inheritance isn’t bad — it’s just easily abused. It’s the right choice when the relationship between classes truly reflects the idea of specialization. If the child class logically “…  ( 9 min )

Most AI-automation posts talk about “agents doing everything.” Forcing the agent to say “I don’t know.” This single constraint changed the entire system. The Problem: Agents Guessing When my workflow automation first went live, the planning agent kept inventing missing context: wrong deadlines imaginary stakeholders nonexistent dependencies Not malicious—just probabilistic. In automation, a confident guess is more dangerous than a clear error. The Fix: A Strict “Blocker-First” Contract I rewrote the agent’s system prompt around one rule: If any required field is missing, return: And I enforced JSON validation at the orchestration layer. If the agent guessed → schema failed → task dropped. If the agent asked a question → I answered once → pipeline resumed. Why This Works This turns the model from a “predictor” into a deterministic validator. No silent assumptions No phantom tasks No hallucinated requirements No speculative routing You force the agent into a request-for-information loop, Result Error rate dropped from 27% → 0% in 48 hours. specs were correct release notes matched reality planning tasks stopped drifting nothing moved forward without defined inputs A single constraint unlocked the entire workflow.  ( 6 min )

There is a hunger within us that no meal can fill—a thirst not just for knowledge, but for meaning, for connection, for the shimmering threads that bind the universe together. It is the restless pulse beneath our daily lives, a call to explore the vast terrain of existence through every medium and method available to us. To learn everything is not to accumulate facts or conquer skills. It is a profound act of faith—faith in wonder, in possibility, in the transformational power of discovery. It is the soulful rebellion against the silent prison of routine and the contained identity. It is to say, I am not merely one thing; I am an unfolding story, infinite in chapters, each waiting for light. Leonardo did not see boundaries between disciplines; he saw a living, breathing universe where art …  ( 7 min )

WTF is this: Machine Learning Explainability Imagine you're at a magic show, and the magician makes a stunning prediction about your future. You're amazed, but also a bit skeptical – how did they do it? Now, replace the magician with a machine learning model, and the prediction with a complex decision. That's where Machine Learning Explainability comes in – it's like demanding the magician to reveal their secrets, but instead of a magic trick, it's an artificial intelligence (AI) algorithm. What is Machine Learning Explainability? In simple terms, Machine Learning Explainability (MLE) is a set of techniques and methods that help us understand how machine learning models make their predictions or decisions. Think of it like a "black box" – you put in some data, and the model spits out an an…  ( 11 min )

👋 Introduction MongoDB is a popular NoSQL database designed to store and manage data in a flexible, document-based format using JSON-like documents. Through this hands-on task, I learned how to: Install and set up MongoDB (locally or via cloud using MongoDB Atlas) Import datasets and store records Perform CRUD operations (Create, Read, Update, Delete) Export query results for further analysis This activity helped me understand how real-world data can be stored, queried, and analyzed efficiently using a NoSQL database. ⚙️ Installation Steps I installed MongoDB using MongoDB Compass, which provides a user-friendly graphical interface for database operations. 📂 Importing Dataset Next, I imported my dataset — the Yelp Reviews Dataset downloaded from Kaggle. 💻 Performing Queries 2️⃣ Top 5 businesses with highest average rating 3️⃣ Count reviews containing the word “good” 4️⃣ Get all reviews for a specific business ID 5️⃣ Update a review 6️⃣ Delete a record 📤 Exporting Results After running each query, I used the Export Results feature in MongoDB Compass to save my outputs. 🎓 Conclusion This MongoDB hands-on activity gave me practical experience in managing NoSQL data. Create and manage collections Perform CRUD operations Query and filter data using expressions and patterns Export and visualize real-world datasets MongoDB’s flexible schema and JSON-based structure make it an essential tool for Data Engineers and Analysts, especially when handling large, diverse datasets where relational models are less effective. It’s a valuable skill for anyone interested in data pipelines, analytics, or backend engineering.  ( 7 min )

As a developer, I'm always looking for ways to build impactful projects. One of the most powerful applications of AI is its ability to make the digital world more accessible. I was inspired by Microsoft's mission to empower everyone, so I built a simple web app that helps describe the world for those who are visually impaired. This application uses Microsoft Azure AI Vision to generate human-readable captions for any image you upload. And the best part? We can build the entire web app in about 30 lines of Python using Streamlit. Let's get started! What You'll Need Python: Make sure you have Python 3.7+ installed. An Azure Account: You'll need one to create an "AI Vision" resource. You can get a free account to start. A Few Python Libraries: We'll install them with pip. pip install streamli…  ( 10 min )

When I first started writing Python code, I relied almost entirely on print() statements to figure out what my program was doing. It worked, at least until my projects got bigger. Once I began building real applications with multiple modules, background tasks, and user interactions, the flood of print() outputs became a nightmare to manage. That’s when I realized I needed something more structured, more scalable, I needed logging. Logging is essentially your program’s way of keeping a journal. Instead of dumping random text to the console, you record meaningful messages that describe what your application is doing, when it’s doing it, and, most importantly, what went wrong when things break. A well-placed log message can save you hours of debugging. The power of logging it’s not just about…  ( 19 min )

I've made a few tutorials on Signal Forms now, and I've seen the comments. Some of you said the old Reactive Forms way is just as good, or you just still like it better. And I get it. Maybe the benefit hasn't been obvious. So today, I'm going to show you a real-world form (the kind that gets messy fast) and we're going to rebuild it using Signal Forms. By the end of this post, hopefully you'll see the advantage, not just hear me say it. What This Form Needs to Do For this demo, we're going to work with an existing form that allows a user to create an account: When I switch this account type to Business, we automatically get a Company Name field added: This is what we call conditional form structure. Super common, but can get super messy. Then we have a password field with …  ( 15 min )

This is a submission for the Agentic Postgres Challenge with Tiger Data I recently had a chat with a friend who works in an e-commerce company, and he was complaining that his company spent a fortune on an AI Customer Service application, only to see an increase in user complaints. I asked him what was going on, and he showed me a real conversation: User: "I want to return this laptop. Also, I wanted to ask, how does the warranty work if I exchange it for a new one?" AI Customer Service: "Okay, I can process the return for you. Please provide your order number." User: "??? What about my warranty question?" AI Customer Service: "Sorry, how can I help you?" Here is where the problem with router-based Conversational AI is, which routes messages to agents who own specific topics and tasks. The…  ( 10 min )

I’d been one of those people who talk about Bitcoin like they’ve used it forever but, in reality, I hadn’t done much beyond watching the charts and reading threads. It was all theory until it was not. One afternoon, I was at a crowded electronics repair shop. I was looking around the faded signs and suddenly stopped at a sign saying "Bitcoin Accepted(Lightning Only). The guy behind the counter, probably the owner, seemed quite experienced; he might have seen it all: phones, printers, and a few individuals like myself attempting to appear tech-savvy. “Does that actually work?” I asked. He gave a half-smile. “Depends on who is trying to pay.” Challenge accepted. I took out my phone and opened the Lightning wallet I'd been meaning to try for weeks.

Remember when creating a simple data class in Java felt like doing some sorts of heavy labor? A handful of fields, 100 lines of code (well, not 100 lines, but is pretty close), and the existential dread of knowing you'd have to do it all again, even with the help of IDE? Yeah, Java 16 finally said "our bad" and gave us Records. If you're still writing POJOs like it's 2010, buddy, we are not the same. A real life use case: You want to store a name, age, and email. In the old days, you'd write a class, add fields, generate getters, generate setters (even though you don't want them), generate equals(), generate hashCode(), generate toString(), and then realize you forgot to update equals() after adding a new field. The reviewers told you to update. You hate yourself. Now? You write this: pub…  ( 10 min )

Sometime ago, I created an MCP server with C#. It was just a basic project I was trying to learn how MCP works, and I followed this Microsoft blog This blog is not a step-by-step tutorial on how to create an MCP server, but more about what I think of MCP after building one. Now, about why I don’t really love MCP. I don’t hate it — it’s just “okay” for me. AI is powerful, but it’s still not fully accurate or secure. If you’ve worked with AI before, you know how easily it gets confused or stuck repeating the same thing. MCP depends heavily on natural language, which makes it even more unreliable in real use cases. For example, let’s say you build a simple MCP tool that just adds two numbers. When you connect your AI agent and ask, “Can you add 1 + 1?”, there’s a high chance the AI will just …  ( 7 min )

Please give me star ⭐ if this is helpful for your work. Github Repo: bigdata5911/schema-guided-reasoning I came across (and tried out) a really interesting project called Schema-Guided Reasoning (SGR) — a small but powerful demo showing how to make AI agents that can reason, plan, and take action using structured logic. Instead of just chatting, this agent can actually do things — issue invoices, send emails, or apply business rules — all based on clear, validated schemas. It’s a great example of how you can combine reasoning with structured outputs to make AI more reliable and explainable. The idea behind SGR is simple but clever: instead of letting an AI respond freely in text, you guide its reasoning through a schema — basically, a blueprint that defines what kind of outputs it can prod…  ( 8 min )

Short URLs look simple, right? But designing a scalable URL shortener that can handle millions of requests per second is an entirely different game. I wanted something lightweight, fast, and globally unique — without depending on auto-increment IDs or UUIDs. That’s when I discovered the power of Snowflake IDs and Base62 encoding. Why Snowflake IDs? Traditional databases can’t safely generate sequential IDs once you scale across multiple servers. You risk collisions or need heavy synchronization. Snowflake IDs solve that beautifully. 64-bit unique identifiers that combine: Timestamp (for order) Machine ID (to avoid overlap) Sequence number (for uniqueness) This way, every short URL gets a unique, time-ordered ID — even if generated across different instances. So, for example: snowflakeID = 177101848939540480 looks huge, but it’s guaranteed unique and sortable. Base62 Encoding – Making IDs URL Friendly A Snowflake ID is long and not URL-friendly. abc123, I used Base62 encoding, which uses: 0-9, A-Z, a-z That means: Every number turns into a short, readable string. No weird characters — safe for URLs. Compact and consistent across systems. So, 177101848939540480 → "bA7zD4" Neat, right? Bitly and TinyURL generate their neat short codes. Why Microservices? I also split the system into small services: ID generator Redirect handler Analytics tracker Each service runs independently, making it easy to scale horizontally as traffic grows. Full Breakdown In my full post, I’ve explained the entire architecture, scaling decisions, database design, caching strategy, and microservice communication flow in depth. 👉 Read the full article here: Designing a Scalable URL Shortener — Snowflake IDs, Base62 Encoding, and Microservices Even a “simple” project like a URL shortener can teach powerful lessons about distributed systems, unique ID generation, and real-world scalability.

As developers, we've all dealt with buggy third-party scripts. Consent Management Platforms can be particularly frustrating. Let me share the common issues I've encountered and how SeersAI's Google Gold Certified solution addresses them. Many CMPs tank your page load speed. They add heavy JavaScript files that block rendering. Users see a blank screen while the consent banner loads. I've debugged sites where the CMP added 3+ seconds to load time. That's unacceptable in 2025. SeersAI loads asynchronously. The banner appears without blocking other page elements. Their script is optimized and uses minimal resources.

I've been studying computer science for some time, and I always assumed I had a solid grasp of how computers work. They process data, execute programs, and occasionally freeze when I overload them with too many Chrome tabs. Then I started reading about supercomputers, and suddenly everything I thought I knew felt tiny. The scale, the speed, and the complexity were on a completely different level. It all began with a project for my Parallel Computing class. The assignment seemed simple: pick two supercomputers from the TOP500 list and compare them. I went to the site and started scrolling.

For years, rollups in blockchain have been the industry's best answer to Ethereum's scalability problem. They process transactions faster and cheaper by moving computation off-chain, then posting batched results back to Layer 1. However, even the most efficient rollups charged $0.50 to $2.00 per transaction during peak times, making them too expensive for everyday applications like social media, gaming, or micropayments. The reason is surprisingly simple. While rollups in blockchain handle execution efficiently, they still need to store transaction data somewhere permanent and verifiable. Ethereum's block space costs around $0.50 per kilobyte, and data availability expenses consume up to 90% of rollup transaction fees. This bottleneck has limited what Rollup as a Service providers could of…  ( 9 min )

Hi all, I'm writing about a tool I've built. It's called SpinnyLights. In a nutshell, this thing produces positive-only recognition based on your public github activity. Like, all your public GitHub activity ever. It cites proof for the statements it makes, linking to GitHub issues/pull requests/commits/files/etc. Here are some examples: https://spinnylights.com/Tooluloope https://spinnylights.com/mastacontrola https://spinnylights.com/t0gun https://spinnylights.com/wayneworkman (my own) The slogan, "by consent" means you have control over your recognition visibility and other aspects. You approve before it goes live, and you can unpublish anytime. This separates SpinnyLights from other similar tools that don't gather consent. The idea is to use your SpinnyLights recognition to: show people what you've been up to. Feel good about your accomplishments and journey. submit as candidate-supplied material to job applications. link recruiters to it and say "Here's what I've done" another public URL to put into that "other remarks" box or that "website" field on job applications. Am I selling to you? yes and no. There are three free recognitions available to whoever takes them each day. That limit resets each day. If you don't want to wait, you can pay $29. I hope you all find it useful. I'd also appreciate any feedback that you have. Visit the site and get your recognition: https://spinnylights.com/ I look forward to seeing your SpinnyLights recognitions! Thanks, Wayne  ( 6 min )

This module was built entirely on my own time using my personal laptop, personal AWS accounts, and personal funds (RIP my credit card). All development and testing was done independently using my own resources. Just released v0.2.1 of my Terraform module that does autonomous CloudWatch Alarm triage using AWS Bedrock, and I've got to say, it's been a real eye-opener seeing it in action. The module essentially gives your CloudWatch alarms the ability to investigate themselves when they go off. Here's the thing about production incidents, when an alarm fires at 2am, whoever gets paged is coming in cold. They're scrambling to understand what's happening, digging through logs, checking metrics, trying to piece together the story while the clock ticks and stakeholders start asking questions.

Are you paying thousands of dollars for running Lambda functions in your AWS accounts. That's a common scenario where you start of Lambda functions as it is cheap but over time when you invoking the Lambda thousands of times, your bills just go high and you can't figure out how to reduce it. In this article, I will talk about steps you can take to reduce the cost. Before we can reduce the cost, we need to understand where the cost is coming from. Let's go through a few metrics. Invocations: How often are the Lambda functions being called? Is the architecture correct? Do you need to call it that often. Duration: How long are the functions running for each invocations? Does it need to run for so long? You can optimise but updating the memory configuration which allow the Lambda to run …  ( 8 min )

As developers, we spend countless hours in terminal emulators. Whether we're SSHing into remote servers, running build scripts, or managing deployments, the terminal is our second home. But most terminal applications feel outdated, lack modern features, and don't prioritize security. That's why I built Kerminal—a modern, feature-rich terminal emulator with advanced SSH management, multi-device synchronization, and enterprise-grade encryption. In this article, I'll share the journey, the technical decisions, and the lessons learned. The story of Kerminal started with a simple, urgent need: I needed a terminal app that could manage my SSH connections and sync them across devices. Like many developers, I was juggling multiple servers and constantly switching between my work laptop, personal m…  ( 12 min )

Yesterday, I explained the OSI model and why each layer matters for AWS. Today, I show you what switches and routers actually do. Here is what clicked for me, Networking is not magic. It comes down to three tables and three actions. That is it. Once you understand these tables, you understand how data flows from your laptop to AWS and back. Let me show you. Before we dive into how they work, you need to understand what they do. Switches: Move data WITHIN networks Your home Wi-Fi? That is a network. All your devices (laptop, phone, printer) connect through a switch (often built into your router). The switch handles communication between devices on the same network. Routers: Move data BETWEEN networks Your home network is separate from AWS's network. A router connects these different network…  ( 17 min )

Fetching data and loading components in React has traditionally revolved around the useEffect and useState hooks, requiring manual management of loading and error states. While effective, this often leads to boilerplate code. React Suspense, combined with features like React.lazy, offers a more powerful, declarative alternative for handling asynchronous operations. Let's explore how Suspense revolutionizes both data fetching and code splitting. useEffect and useState In the conventional pattern, the component is responsible for tracking its own loading and data state. We use useState to hold the data and a loading flag, and useEffect to perform the fetch operation. import React, { useState, useEffect } from 'react'; function UserProfile({ userId }) { const [user, setUser] = useState(n…  ( 9 min )

Securing secrets in your Docker-based app is critical—but the official Docker "secrets" feature is tied to Swarm, and the popular *_FILE pattern isn't supported by every image.

Hey everyone 👋🏾 Godfred Kwesi Agyeman (@kwesithedev), a full-stack JavaScript developer from Ghana 🇬🇭. I’ve been on a mission to turn my ideas into real, working products — and to grow into a developer who can build things that actually solve problems. I’m currently learning through the FullStackOpen course, but most of my focus right now is on building projects and real-world experience. My current stack includes: React & Next.js for frontend and full-stack apps Node.js for backend APIs Supabase & Firebase for auth and data MongoDB (and learning PostgreSQL + Prisma soon) TailwindCSS for fast, clean UI design React Native for mobile apps I’m also getting deeper into payment integrations — things like Stripe, Paystack, and Flutterwave — because I want to build products that can actually transact and make money. Why I’m Here To be honest, I’ve dealt with imposter syndrome and a lack of resources — but I’ve learned that building real projects is the best way to learn and grow. So this space (and this post) marks the start of me: Sharing my journey as I learn, build, and grow Posting about what I create and what I learn from it Connecting with other devs who are doing the same I believe that being open about the process — the wins and the mistakes — helps others and keeps me accountable.

Back in the day, we used XMLHttpRequest to call APIs. Fetch API instead — it gives us a JavaScript Interface to handle HTTP request more cleanly. Let's take a look at how to use it. Here's the basic flow: Specify the URL you want to call. The first then gets a promise — you use response.json() to parse the response as JSON. The second then handles the parsed JSON data. If the fetch runs into an error that's not a 4xx or 5xx response, the catch block will handle it. fetch("http://example.com/movies.json") .then(response => { return response.json(); }) .then(json => { console.log(json); }) .catch(error => { console.error(error); }); If the server responds with JSON, you'll need to call response.json() to parse and return it as JSON. arrayBu…  ( 8 min )

While grinding through the monumental JuggleBee upgrade, one of the recurring debates was: what do we modernize, and what do we leave the heck alone? Plenty got a shiny new coat of paint (see my earlier posts for all the juicy details), but one area I deliberately left untouched was the frontend JavaScript. These days, jQuery is seen as a relic of a bygone era — a noble steed well past its sell-by date. Hotwire now ships as the Rails 8 default, and heavyweight contenders like React and Vue have taken over the frontend spotlight. So why didn’t I replace it with Hotwire or Stimulus when doing the big Rails 8 overhaul? Because honestly... it still slaps.

Most people think prompting is about “typing better sentences into ChatGPT.” That mindset is exactly why their prompts fail. The truth is uncomfortable, but it needs to be said: Most people don’t get bad AI outputs because AI is limited; they get bad outputs because their thinking is limited. Prompting isn’t a trick. Once you understand this, AI stops feeling like a gamble and starts becoming a precision tool. Let me show you why most prompts fail, and the 5-step method I use to fix them. The Real Reason Prompts Don’t Work Weak prompts have one or more of these problems: Vague Input: “Write an article on AI.” No Context: AI doesn’t know who you are, who it’s for, or why it matters. Zero Constraints: Without boundaries, AI produces generic filler. No Expected Outcome: If you don’t define “g…  ( 9 min )

Beyond the Limits: Super-Resolution Ultrasound with AI Imagine needing crystal-clear vision, but your glasses only allow a blurry view. Traditional ultrasound faces a similar challenge: low-cost sensors often capture limited frequency ranges, resulting in fuzzy images lacking crucial detail. What if we could use AI to digitally enhance these blurry images, revealing hidden structures and improving diagnostic accuracy? The core idea is to train a deep learning model, specifically an autoencoder leveraging transformer architectures, to learn the relationship between low-resolution and high-resolution ultrasound data. The model acts like a sophisticated "translator," taking in the limited data and reconstructing a far richer image. It's akin to teaching an AI to "see" the missing frequenci…  ( 7 min )

AWS just released a new service in Builder Center, AWS Capabilities by Region. I believe this will be a service that many might miss, but for those who know it exists, it will be integral when deciding where to place workloads when planning for migrations, disaster recovery regions, and expansions. So what does the service do? It lets you compare what services and features exist in different regions. And this will make planning much easier and help avoid unnecessary work in regions that won't support your workload. For example, it is not uncommon when implementing a disaster recovery (DR) region that you, in the middle of setting it up, run into issues where a service/feature available in the main region doesn't exist in the DR region, and you need to pivot to another region. And by using this service in the planning stage, we can avoid issues like that. The main feature of the service is the Service and features, where you can compare different regions and see what services and features they offer. To use it, you select what regions you want to check and either select all services or specific ones. You will see a comparison of the availability of the service and its features between the regions. One other great feature is that you will also be able to see when a service/feature is planned to be deployed to the region. When I have used it, I have added all the services I am using, then selected the region I am currently in, and then selected the regions I am planning to migrate to. I quickly get an overview of which services and features will and will not work. Another feature of the service is to see what API operations are available in each region and compare the regions. You can also view and compare available CloudFormation resources in the regions. This is a great new service that I will use a lot when planning where to place workloads. It will make it easy to get an overview of where the resources you need are available.  ( 7 min )

With help of AI, you can draft a solid research proposal in just a couple of hours instead of days. Here's how: Let's say, we need to write a research proposal on NLP (Natural Language Processing), classifications of social media posts. Step 1: Come up with some research ideas Notes: Browse more sources like ACM NLP conference papers, Google Scholar, ScienceDirect, etc if needed. Open all the papers on new tabs in Comet. Now I have 40 papers to read through, not manually, but with AI assistance! Talk to "Comet" with a prompt: Research all open tabs and give me 10 research questions about classifications of social media posts. Cite the sources. Step 2: Narrow down to 3 research ideas Suggest me a research proposal title and abstract based on the following 3 research questions: [Refined Research Question 1] [Refined Research Question 2] [Refined Research Question 3] Step 3: Prepare a working directory research-proposal/ abstract field included Write the research proposal Help me write a research proposal. Save your response to main.tex Create a Makefile to compile the LaTeX document with targets: all: compile the document Research questions: [Refined Research Question 1] Background Only cite the papers from the references.bib file, don't make up any citations. Refer to samples/research-proposal1.tex and samples/*.tex for formatting and structure guidance. Step 5: Humanize and finalize Humanize the text.

Testing is an important part of building software, but many developers, including me, sometimes skip it. In this post, I want to share how I added tests to my Python project, the tools I used, how I set them up, and what I learned along the way.

It’s easy to use, supports simple tests, and has many features like fixtures and parameterized tests. pytest-cov: This plugin works with pytest to show which parts of your code are covered by tests. It helps you find which lines are being missed. I also used pytest-watch (ptw) to automatic…  ( 7 min )

The Meme You Cant Unsee Old security: “Check IDs.” New security: “Check IDs and the bag.” The meme is the message. We don’t just ask who is calling our systems—we open the bag and prove what’s inside. And that bag must contain only policy-approved tooling, cryptographically attested, no surprises, no freebies. Call it EnvSecOps if you want a name. Practically, it’s the painfully obvious next step: No attested, policy-approved bag → no token. The bag = the execution environment: image, toolchain, configs, helper scripts. Policy-approved = explicit allowlist: pinned digests, permitted binaries, known configs. Attested = cryptographically proven: signed statements that the environment only contains those allowed artifacts. If anything unapproved is in the bag? Deny. :latest. No “temporary”…  ( 8 min )

Mutually Exclusive Unions in TypeScript (and why ExclusifyUnion rocks) When modelling data, we often want either one shape or another, never both at once. This is the essence of a mutually exclusive union. In TypeScript, that means writing unions where accessing properties becomes ergonomic without defensive checks everywhere. This post shows a neat pattern using ?: never, why it doesn’t scale, and how type-fest’s ExclusifyUnion helper elegantly solves this problem. Mutually exclusive unions help us distinguish the shape of a given object. Take the following example: type Dog = { bark: () => void; }; type Cat = { meow: () => void; }; const vocalize = (animal: Dog | Cat) => { if ("bark" in animal) { animal.bark(); return; } return animal.meow(); }; Once we’ve checked…  ( 9 min )

Stored Procedure A stored procedure is a precompiled collection of SQL statements (and sometimes control logic) stored in the database. It’s like a function that can be called whenever needed. It can accept parameters such as input and output, and is also often used for complex logic, such as loops. CTE (Common Table Expression) A CTE is a temporary named result set you can use within a single query. Think of it as a short-term, readable alias for a subquery. It exists only during query execution. CTE's make complex queries easier to read and maintain. Subquery A subquery is a query nested inside another query; in other words, it is like a query within a query. It can appear within the SELECT, FROM, or WHERE clause, and it executes each time the main query is run.  ( 6 min )

WebForms Core technology consists of a client-side library called WebFormsJS and a server-side class called WebForms and the connection between the two. In this technology, you only need to add the WebFormsJS library in the head section of HTML and do the development in the WebForms class on the server in a command-oriented way. So the WebFormsJS library only plays a communication role and you do not develop it! The connection between the two is automatic and has been tested in advance and the probability of errors is very low; However, we at Elanat have added the unit testing tool in version 2 of WebForms Core technology. Unit testing is a critical part of modern web development, ensuring that components behave as expected and changes don’t introduce regressions. Before release of WebFor…  ( 9 min )

Google has expanded Opal, its no-code AI app builder, to more than 160 countries. Opal lets anyone build AI mini-apps using natural language instead of code, and it is positioned as the fastest way to turn an idea into a working AI tool without APIs, backends or prompt-chaining frameworks. That makes Opal important for developers not because it replaces engineering, but because it changes who can ship AI tools and how fast internal apps will now be created. Most AI products today are either: chat interfaces wrapped around a single model low-code builders connected to external APIs RAG pipelines that still require storage, ingestion and maintenance Opal creates a fourth category: AI apps built entirely through text instructions, no code, no infra, no workflow engine required.

I've been through a dry spell or two. The early 90's was a pretty tough time for someone new to the industry. The dot com bust also led to belt tightening in the industry. There has always been an ebb and flow in demand, but those who eat and breath software sailed through those seas. This time it's fundamentally different. Life has been pretty good for software developers over the last 40 years, but life does not owe software developers anything, and perhaps we are nearing the end of the gravy train. Up until 1900 the horse was the primary mode of transportation. In a space of about ten years the car replaced horses in volume. Horses were no longer required. Sure, you can still find them today, in horse racing or on tourist ventures perhaps. But there is no law of nature which says "ther…  ( 8 min )

More than five years ago, I sat in yet another meeting listening to someone say, "You know what we really need? A gold layer for our data lakehouse." Heads nodded around the table. Everyone agreed it was a smart idea. Obviously necessary. Then everyone went back to their desks and did nothing. The idea wasn't revolutionary. It was sitting right there on the surface: visible to anyone who looked at our Bronze-Silver architecture and asked, "How does the business actually use this data?" But here's what I learned: Ideas are everywhere. People who actually build them are rare. That day, I stopped waiting for someone else to make it happen. I proposed the initiative, assembled my team, and we started building. This is the story of how we completed a data lakehouse architecture that nobody mand…  ( 13 min )

Property-Based Testing with Hypothesis: The Data You're Throwing Away Part 3 of the Multi-Agent Development Series Part 1: Can 5 Claude Code Agents Work Independently? Part 2: The Reality of "Autonomous" Multi-Agent Development This post explores coding with Claude Code and exploring what works and what doesn't in this hybrid new coding model. when and how it is most useful for a Human to direct the AI Agent. We added property-based testing with Hypothesis. Agent ran 7000+ random scenarios, found multiple edge cases, Hypothesis shrank them to minimal failing examples, then agent discarded 99% of that data by reducing max_examples without capturing anything. User had to correct the agent 3 times before it understood: "It's like you're a genius and brain dead at the same time." The lesson:…  ( 17 min )

Recently, I began auditing my AWS account and I saw how secure I had made it when deploying applications and managing external access. I even wrote a blog post recently on how people should adopt OpenID Connect to authenticate in CI/CD pipelines and deploy their applications to AWS.Recently, I was deploying a Terraform script locally and I could not authenticate to AWS. I figured out my static keys were expired and I needed to generate another. That was when I realized my real admin access wasn’t secure at all. I was still moving static keys around for admin access, and they were permanent. I checked the IAM portal to see if I could find a solution to eliminate this completely, and I found a much better approach by using a federated identity through IAM Identity Center. I always thought on…  ( 9 min )

You’ve decided to master Python. You’re drawn in by its reputation for clean syntax and its dominance in fields like data science, machine learning, and generative AI. But as you stand at the starting line, you’re hit with a barrage of preliminary questions that feel more complex than the coding itself: Should I install Python locally or use a cloud service? Which IDE—PyCharm, VS Code? What even is a Jupyter Notebook? This initial paralysis of choice is a universal experience. The path from novice to professional isn't just about learning syntax; it's about making strategic decisions about your tools and workflow from day one. Many tutorials rush past this crucial setup phase, leaving developers to stumble through mismatched environments and frustrating configuration errors. This guide is …  ( 14 min )

Simulação Real: Quanto Sua Família Economizaria com Portabilidade de Energia Introdução: O Poder dos Números na Conta de Luz Você já parou para calcular quanto sua família gasta com energia elétrica por ano? De acordo com dados da ANEEL atualizados em Janeiro de 2025, o Estado do Rio de Janeiro apresenta a tarifa convencional média mais cara do Brasil, com valores superiores a R$ 1,40 por kWh. Em contraste, o Rio Grande do Sul possui a tarifa mais barata (R$ 0,41/kWh). Mas aqui está a boa notícia: com 25.966 novas unidades consumidoras em 2024, o mercado livre de energia brasileiro atingiu a marca de 64.497 unidades consumidores, crescimento de 67%, recorde histórico.

If you want to configure the Dataverse MCP Server as described in the official Microsoft Learn article, you'll need to write in your mcp.json file an url with the following exact format (without the line breaks, of course): https://make.powerautomate.com/environments/ 59fd5b0e-f1e3-4f86-920d-509f44cb1846/connections ?apiName=shared_commondataserviceforapps &connectionName=263a3d1e-1279-45f6-a593-070f9efaaad3 The tutorial instructs you to create a connection via make.powerautomate.com, and then take the URL from the connection page. If you do it exactly as stated in the official docs, the URL you'll get has this form: https://make.powerautomate.com/environments/ 59fd5b0e-f1e3-4f86-920d-509f44cb1846/connections /shared_commondataserviceforapps /263a3d1e-1279-45f6-a593-070f9efaaad3/details The fact is that URL, put in the mcp.json file, won't work 😡🤬. You need to tweak the url manually in the following way: take the first part of the url, from https:// to connections replace the / after connections with ?apiName= replace the / after shared_commondataserviceforapps with &connectionName= remove the leading /details And you're ready to go. 🙏🏻 Hope this helps you too!  ( 6 min )

What we learned when 5 "independent" AI agents needed constant human orchestration Part 2 of the Multi-Agent Development Series We set out to prove AI agents could work independently with zero coordination. The zero-conflict architecture worked perfectly (100% auto-merge). But "autonomous" agents? That was the illusion. What actually happened: ✅ Zero merge conflicts (architecture win) ❌ Constant human orchestration required (autonomy myth) ✅ Property tests found a 12x efficiency bug (agent + human win) ❌ But only because human asked the right questions (human essential) The real lesson: The value isn't "autonomous agents." It's well-orchestrated human-AI collaboration. In Part 1, we described an experiment: 5 parallel AI coding agents Each working on independent test improvements Zero-conf…  ( 12 min )

Special education teachers play a vital role in pullout classrooms, where students with diverse learning needs receive individualised or small-group instruction outside the general education setting. This approach allows educators to provide focused attention, specialised interventions, and customised teaching strategies tailored to each student’s learning goals. Read More In a pullout classroom, teachers assess students’ strengths and challenges, design lessons that complement their Individualised Education Programs (IEPs), and use adaptive methods such as multisensory instruction and assistive technology. These sessions help students build confidence and reinforce foundational skills in literacy, maths, and social-emotional development. Collaboration is another key aspect of the pullout model. Special education teachers work closely with general education staff, therapists, and parents to ensure consistent progress across all environments. They also monitor and document student growth, adjusting instructional strategies as needed to maximise success. Ultimately, pullout classrooms create a supportive space where students can learn at their own pace and receive the specialised assistance they need to thrive academically and socially. The role of special education teachers in this setting is not just instructional—it’s transformative, fostering inclusion and empowerment for every learner.  ( 6 min )

Oklou jetted in from Paris with her five-month-old in tow to rework four tracks from her debut album, Choke Enough, for NPR’s Tiny Desk. She and arranger Casey MQ ditched the synths and autotune, leaning into piano, acoustic guitar, a seven-foot marimba and an eight-piece choir. They even cranked up the atmosphere with bubble-wrap fire crackles and makeshift effects to keep the sonic adventure alive. The set—featuring stripped-down versions of “ict,” “blade bird,” a bare-bones “harvest sky” led by recorder, plus the unreleased “what’s good”—turns Oklou’s electronic pop into reflective, acoustic folk. It’s an intimate, DIY twist on her sound that feels both fresh and deeply personal. Watch on YouTube  ( 6 min )

If you've ever run a Django site, you've probably seen the endless stream of bots trying to brute-force your /admin/ page. After watching my logs fill up with failed login attempts, I decided to do something about it. Attackers know Django uses /admin/ by default. They hammer it with credential stuffing, brute force attacks, and automated scanners. While rate limiting helps, it's reactive. I wanted something proactive. I built HoneyGuard, a Django package that creates fake admin login pages (honeypots). Here's how it works: Move your real admin to /secret-admin/ (or whatever), and let HoneyGuard serve a convincing fake at /admin/. Attackers waste their time, and you gather intel.

In today’s construction landscape, compliance isn’t just about avoiding fines—it’s a strategic advantage. Contractors working on public works projects face an increasingly complex set of wage, documentation, and reporting obligations. From Davis-Bacon Act requirements to state-level prevailing wage rules, payroll compliance can quickly become a time-consuming and error-prone process if handled manually. Automation is changing that equation, helping construction firms protect their margins, maintain compliance, and gain a competitive edge. Construction payroll involves a unique set of variables: multiple job classifications, varying wage determinations, fringe benefit calculations, and fluctuating crew schedules. When all of this information lives in disconnected systems or spreadsheets, er…  ( 7 min )

Every week, I review competitors' articles and summarize them in a report. It’s repetitive and not exactly the favorite part of my week. I have been using a few new AI tools, such as Amp, Opencode, and I thought it would be nice to have a tool that could make things easier. So I built "Herctually," an AI research assistant that automates the boring parts. We’ll try to build Hertcually in Go, from model setup to giving it powers like web search, reading, and report writing. But first, let's align on what an agent is. According to Thorsten Bell, an agent is “an LLM with access to tools, giving it the ability to modify something outside the context window“. How I see it is that an agent is a large language model (LLM) that can take actions, not just talk. It can search, write, read, and execu…  ( 14 min )

Writing effective, maintainable, and readable tests is a cornerstone of modern software development. One of the most fundamental and widely adopted design patterns that helps achieve this is AAA: Arrange, Act, Assert. This pattern provides a clear, three-part structure for any test, making it easier to write, understand, and debug. While AAA can be applied across all testing types (unit, integration, end-to-end), we will focus on unit tests to keep the explanation clear and simple. The AAA pattern divides every test method into three distinct sections: Arrange: Set up the necessary conditions and inputs for the test. Act: Execute the code under test. Assert: Verify that the execution produced the expected result. Let's dive into each step: The Arrange step is where you set the stage for yo…  ( 8 min )

Everyone knows companies are using AI to scan resumes now. applicants are using AI to write those resumes. So we get this situation: The applicant uses AI to make their resume stronger. The recruiter uses AI to filter resumes faster. HR uses another AI to detect whether the resume was written by AI. And all of this still ends with: “We’ll get back to you.” It’s weird. And kind of funny. Because for applicants, job searching is emotional: Hope Stress Trying to prove that you’re worth something Taking rejection personally For recruiters, it’s logistical: Way too many candidates Not enough time to review everyone Pressure to reduce the stack quickly So both sides start using AI. But then you get the contradiction: “We can use AI to evaluate your resume, but if you used AI to write it, we might penalize you.” Feels… uneven. We’ve reached a point where the hiring pipeline is basically: AI writes → AI evaluates → AI judges authenticity → humans maybe talk later The process still pretends to be human. AI negotiating with AI about humans. I don’t think this is “bad” or “good.” What do you think?

An incremental journey from Redux modules to intuitive async data management Years ago we adopted Redux to manage the client state, handle the local state, and control data fetching. More recently, we began transitioning to React Query. Redux is primarily designed as a synchronous state manager, while React Query specializes in managing the asynchronous state. Both are agnostic to the underlying fetching library, but Redux requires significant boilerplate to handle async operations, whereas React Query offers built-in patterns that make data fetching, caching, and updating feel more natural. We decided these advantages made React Query a better fit for our codebase. Depending on the size of the application, migrating to React Query can require a significant amount of time.

Accessing AWS in Github Actions Using OIDC Tobiloba Ogundiyan ・ Nov 6 #tobilobaogundiyan #aws #githubactions #cicd  ( 6 min )

In CI/CD pipelines, the normal way to access AWS resources for deployment is to generate long-lived access keys in IAM and store those keys in the repository, but this approach has the following flaws: The keys are long-lived and if they ever leak, an attacker can use them to access your AWS account. The same static keys get reused across many jobs and branches, so it is hard to trace which workflow actually did what. Rotating or expiring those keys requires a manual process, so they usually stay active way longer than they should. OpenID Connect (OIDC), an identity layer on top of OAuth 2.0, solves this by letting GitHub Actions request short-lived, on-demand credentials from AWS using a trusted federation instead of storing static keys. This approach gives the following benefits: …  ( 10 min )

Gemini Deep Research is Google’s most significant step toward AI-native productivity inside Google Workspace. The model can now read Gmail conversations, analyse Google Drive files and combine context across Docs, Sheets, Chat and shared folders without uploads, embeddings or third-party retrieval layers. That single shift turns Gemini from a chatbot into a real workflow engine for developers building gmail ai automations, google drive ai workflows and full-stack google workspace ai systems. Where ChatGPT and Perplexity still require file uploads, API connectors or external RAG pipelines, Gemini Deep Research sits on top of the data that already exists inside an organisation. No ingestion jobs, no manual context injection, no vector database to maintain. The AI sits beside the user, not th…  ( 13 min )

When working on the Automad dashboard, I needed a collapsible and sortable navigation tree for the page browser sidebar — something that would feel like a small file explorer inside the browser. My goal was simple: use plain TypeScript, no frameworks, and rely only on native browser APIs. So I went looking for an existing library. There are countless tree components on npm — but nearly all of them depend on React, Vue, or another frontend framework. I wanted something that works in any context: a small script I could drop into a project and wire up using plain events and DOM nodes. Nothing like that existed. So I built it. What started as a small experiment for the Automad dashboard eventually became a complete standalone library: sortable-tree — a lightweight, dependency-free (well, …  ( 8 min )

When using vite, you have a huge ecosystem of plugins to choose from. If you don't already have a vite app Create one via: pnpm dlx ember-cli@latest new demo-terminal-logging-during-ember-browser-testing --pnpm cd demo-terminal-logging-during-ember-browser-testing I found https://github.com/patak-dev/vite-plugin-terminal by Patak, one of the vite developers! Setting this plugin up an an ember project to get browser-test results in the terminal is quite straight-forward: In your vite config, add the plugin: + import Terminal from 'vite-plugin-terminal'; export default defineConfig({ plugins: [ + Terminal({ console: 'terminal' }), ember(), babel({ babelHelpers: 'runtime', extensions, }), ], }); And QUnit doesn't log to the console in /tests mode by default, so let's add some logging in tests/test-helper.js import * as QUnit from 'qunit'; QUnit.testDone(function (info) { let status = info.failed === 0 ? '✅' : '❌'; let statusText = info.failed === 0 ? 'passed' : 'failed'; console.group(); console.log(`${status} ${info.module} > ${info.name}: ${statusText}`); console.log(` Assertions:`); for (let assertion of info.assertions) { console.log(` ${assertion.result}: ${assertion.message}`); } console.log(''); console.groupEnd(); }); And that's it! Now when you run tests, you'll get output like this: » [vite] connected. » DEBUG: ------------------------------- » DEBUG: Ember : 6.8.1 » DEBUG: ------------------------------- » ✅ example > example test: passed » Assertions: » true: okay » » ✅ ember-qunit: Ember.onerror validation > Ember.onerror is functioning properly: passed » Assertions: » true: Ember.onerror handler with invalid testing behavior detected.

Building Cross-Language TUIs: One Go Binary to Rule Them All A single Go binary can provide terminal UI components for CLI tools written in any language. By using subprocess calls with JSON communication, we reduced UI development time by 3x and eliminated inconsistencies across Python, Ruby, and JavaScript implementations—all while maintaining a 10-50ms overhead that's imperceptible to users. A cross-language TUI (Terminal User Interface) architecture uses one compiled binary to handle all terminal UI rendering for CLI tools built in different programming languages. Instead of maintaining separate TUI implementations in Python (Rich/Textual), Ruby (TTY), JavaScript (Ink/Blessed), and Go (Bubble Tea), you build once in Go and call it via subprocess from any language. The approach works thr…  ( 10 min )

As AI systems continue to consume an increasingly large share of global computing resources, can we say that the pursuit of artificial general intelligence is ultimately a zero-sum game between human well-being and environmental sustainability, or is there a potential for AI to be the catalyst for a more efficient and environmentally conscious technological singularity, one where the benefits of AI outpace the costs and create a virtuous cycle of human progress and environmental stewardship?

Today I focused on improving my data visualization skills using Matplotlib, one of the most powerful Python libraries for creating charts and plots. Visualization is an important part of Data Analytics because it helps to communicate patterns, trends, and insights clearly. Today, I explored how to add labels, titles, colors, and shapes, and also learned about different types of charts used in data analysis. A chart without a title or labels can be confusing. Title explains what the chart is about. X-label and Y-label tell what each axis represents. import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5] y = [10, 20, 25, 30, 35] plt.plot(x, y) plt.title("Sales Growth Over 5 Months") # Chart title plt.xlabel("Month") # X-axis label plt.ylabel("Sales (in thousand…  ( 7 min )

I recently built my own AI agent. Not because I needed one, but because I wanted to see how far I could take the current tools available. It turned out to be surprisingly straightforward, extremely flexible, and genuinely useful. This post will show you what the agent can do and how you can build your own using n8n, without needing to write much code. The agent runs as a simple chat interface where I can ask it different questions and request actions. For example: Ask for the weather in a city. Get my current YouTube subscriber count. Check my recent running stats from Strava. Have it send me an email containing a summary of the full conversation. Here is what the chat looks like in use: This is not necessarily something you must have, but it is a great demonstration of what is possible w…  ( 8 min )

When you ship a typical web service, you instrument it with metrics and traces. Application Performance Monitoring (APM) tells you if requests are fast, if error rates spike, and if your system is behaving as expected in production. You also write unit tests and integration tests to catch regressions before they go live. Those two pillars, pre‑release testing and live observability, are what give you confidence in traditional software. Now we’re implementing LLMs into everything from chatbots to workflow automation. They’re not deterministic functions. What we need is a way to observe and test the qualitative behavior of these models and treat their outputs as first‑class citizens in our quality pipeline. That’s where LLM evaluations (evals) come in. Evals act like unit tests and health ch…  ( 7 min )

Hey dev.to community! 👋 How much time do you spend re-typing the same kubectl, helm, argocd, terraform, or custom script commands every day?

This tutorial was written by James Shisiah. When it comes to databases, the age-old debate never ends: relational versus document. On one side, you’ve got the classic relational database—PostgreSQL—organized, structured, and always insisting that every piece of data belongs neatly in its own row and column. Think of it as the well-disciplined librarian who won’t let you borrow a book without filling out three forms—the emphasis is on organization, structure, and order. On the other side, you’ve got MongoDB, the document database—with flexible schema, and more like a cool café owner who says, “Just scribble your order on a napkin, I’ll figure it out.” Document databases emphasise flexibility, ease, and speed.

El problema oculto detrás de las validaciones masivas Cuando validamos arrays de datos en Laravel usando reglas como unique, el framework realiza una consulta por cada elemento del array. Por ejemplo, si validas una lista de correos electrónicos con la regla unique:users,email, Laravel ejecutará una consulta por cada email. Esto genera lo que conocemos como el problema N+1, un clásico enemigo del rendimiento en bases de datos. El problema ocurre así: Tienes un array con N elementos. Laravel ejecuta N consultas SQL para validar cada uno. A medida que el tamaño del array crece, también lo hace el número de consultas.

💡 Core Idea In DevOps, building automation using Shell or Python scripts is completely different from running automation inside CI/CD pipelines. 🚀 Key Points 1.Understand the Context Gap Shell or Python scripts are created to run on specific systems like an EC2 instance or a local machine. 2.Merge, Don’t Replace Pipelines should not replace your existing scripts. 3.Separation of Responsibilities In real DevOps design, each layer has its own clear responsibility. 4.Why This Matters 🧱 Modularity: Scripts stay reusable and easy to maintain. 🔁 Portability: The same script can run locally or in a pipeline. 🛡️ Security: Secrets are managed safely within the pipeline, not inside scripts. 📈 Scalability: Both scripts and pipelines can evolve independently. 🔍 Observability: Pipelines provide unified logs and build history. 5.Context-Based Example deploy.sh set -e Jenkinsfile pipeline { Here, the pipeline provides the context (environment, credentials, and orchestration), 6.Guiding Principle “Let scripts do the work. Let pipelines decide when, where, and why that work happens.” This approach keeps your automation clean, modular, and context-aware. 7.Real DevOps Insight When you effectively blend scripting and pipelines: You move beyond simple automation into automation architecture. Your workflows become tool-agnostic — reusable across Jenkins, GitLab, or ArgoCD. You create a strong base for Infrastructure as Code and CI/CD as Code. 🏁 Final Thought A DevOps engineer’s real strength is not just writing automation — it’s in architecting it intelligently. Merging scripting and pipelines contextually is how you evolve from an executor to an automation designer.  ( 7 min )

Recentemente, um dev perguntou se dava pra usar Faceted Search com Interactive Grid (IG) no APEX. Por padrão, o APEX só suporta Faceted Search em Cards e Classic Reports, mas com um pequeno ajuste dá pra expandir esse comportamento. Abaixo mostro o passo a passo prático usando a Sample App – Cards como base. 👇 Instale a aplicação de exemplo Sample Cards. Ela já traz uma página com Faceted Search e uma região de Cards. Depois, duplique a região de Cards e altere o tipo para Interactive Grid, dentro de um Tab Container — assim dá pra ver as duas regiões filtrando os mesmos dados. Os facets (como Department, Manager, Job etc.) não são page items comuns, mas ainda armazenam valores de sessão. Isso significa que você pode referenciá-los diretamente na query do IG, usando seus nomes (P12_DEPTNO, P12_JOB, etc.). Crie uma Dynamic Action no evento Change do facet (ex: P12_DEPTNO): Event: Change Item(s): P12_DEPTNO True Action: Refresh Affecting Region: Search Results (IG) Mesmo sem aparecer na lista de itens, basta adicionar o nome manualmente em Page Items to Submit. Depois, use apex_string.split com o separador : na cláusula WHERE: sql where ( :p12_deptno is null or to_char(m.deptno) member of apex_string.split(:p12_deptno, ':') ) P12_SEARCH) Além dos filtros, o campo de busca do Faceted Search (P12_SEARCH) também pode ser usado para refinar os resultados do Interactive Grid. A ideia é simples: o valor digitado nesse campo será aplicado como filtro LIKE em várias colunas do IG — por exemplo: ENAME, JOB, MGR, DEPTNO, MIMETYPE e FILENAME. Basta incluir a condição abaixo na cláusula WHERE da sua query: sql and ( :p12_search is null or upper(m.ename) like '%' || upper(:p12_search) || '%' or upper(m.job) like '%' || upper(:p12_search) || '%' or upper(to_char(m.deptno)) like '%' || upper(:p12_search) || '%' or upper(m.mimetype) like '%' || upper(:p12_search) || '%' or upper(m.filename) like '%' || upper(:p12_search) || '%' )  ( 7 min )

Yeah you read right. I am still kind of processing it, since it's an actual "high" paying office job. Some context: I was about to give up on finding a "computer" or "media" job.

I run OpenPanel.dev, an open source, privacy friendly analytics tool. So our own dashboard kind of has to feel fast. If your analytics app is slow, nobody will use it. For a long time that dashboard ran on Next.js. I have used Next since the early days. It made SSR feel easy. You wrote some React, added getServerSideProps, shipped it, and it worked. No deep framework knowledge needed. That version of Next was nice. Then the App Router arrived. Then React Server Components. And everything started to feel... wrong. The idea behind RSC is clever. In practice it turned our app into a puzzle.

I once had a dev partner struggling to make good deliveries. After some time talking about the project, he opened up about feeling unable to speak freely in meetings, the pressure of being new, and the fear of being fired. The solution: Create opportunities for him to talk in meetings and scheduled frequent 1:1s. Care about your partners devs, designers, QAs. If you're a tech lead, do 1:1s to understand their struggles, project difficulties, and yeah, how they're doing in life. You don't need to know everything about them, but create a relationship where they can say when something doesn't feel right. Even being an IC (Individual Contributor), you can have 1:1s with your colleagues. The Benefits Are Real: Your partners know more about you.

I built a fully local Retrieval-Augmented Generation (RAG) system that lets a Llama 3 model answer questions about my own PDFs and Markdown files, no cloud APIs, no external servers, all running on my machine. It’s powered by: Streamlit for the frontend FastAPI for the backend ChromaDB for vector storage Ollama to run Llama 3 locally The system ingests documents, chunks and embeds them, retrieves relevant parts for a query, and feeds them into Llama 3 to generate grounded answers. It started with a simple frustration, I had a bunch of private PDFs and notes I wanted to query like ChatGPT, but without sending anything to the cloud. don’t know your documents. RAG changes that, it gives the model a “working memory” by feeding it relevant chunks of your data each time you ask a question. So, …  ( 9 min )

Search isn’t just about finding information anymore — it’s about understanding intent. That’s where AI Powered Search Optimization comes in. Traditional search looks for pages with that exact phrase. This ability to interpret meaning instead of text is the foundation of AI Powered Search Optimization. From a technical perspective, AI search is powered by three pillars: 1. Natural Language Processing (NLP) NLP allows systems to interpret human language in a structured way. Libraries like spaCy, NLTK, and Hugging Face Transformers give developers powerful ways to analyze and understand language. In short: NLP makes queries smarter. 2. Semantic Search with Vector Embeddings Semantic search transforms text into vectors — numerical representations that encode meaning. Instead of looking for li…  ( 8 min )

Building a SaaS is messy. You’re coding, testing, talking to users, and somehow trying to market your product—all at the same time. Some AI tools actually make life easier, but only if you use them in real, practical ways. Here’s what’s worked for me and other founders I know: Research Smarter, Not Harder Quick Visual Concepts Copy That Actually Converts Docs Without the Headache Landing Pages in Hours Video Made Simple Automation That Actually Works **Community & SEO Wins Support Bots That Don’t Suck Presentations Without Pain UI/UX Testing Fast Marketing & Design Audio & Onboarding Idea Validation Productivity Lifesavers Social Media Without Stress The point: AI isn’t magic. It’s a tool. Use it where it removes friction, saves time, or gives insight. Start with one workflow, test it, and grow smarter—not just faster.  ( 7 min )

Media queries still work. But they’re not always the best tool when it comes to small layout changes. I ran into this while building a popup that needed to shrink smoothly between 750px and 950px. I added three media queries. It felt clunky. That’s when I gave clamp() another look. Turns out, clamp() lets you describe responsive behavior in one line. It’s supported by 96% of browsers and works for any CSS property that accepts a unit (font, spacing, etc.) The syntax looks like this: font-size: clamp(16px, 2vw, 32px); or if you're using rem font-size: clamp(1rem, 2vw, 2rem); This means: Never go below 16px Never exceed 32px In between, scale based on viewport width It’s simple, except tuning the values feels awkward. The “preferred” value must be a fluid unit like vw or vmin, and the curve is linear between min and max. There are many small tools, I personally like this one to preview and fine-tune clamp expressions: https://design.dev/tools/clamp-generator/  ( 6 min )

Picture this: your QA team just rolled out a comprehensive new test suite; polished, precise, and built to catch every bug. Yet soon after, half the tests fail. Not because the code is broken, but because the design team shifted a button slightly. And even when the tests pass, users still find issues in production. A familiar story? End-to-end testing was meant to bridge that gap. This is how teams verify that complete user workflows actually work the way users expect them to. It's testing from the user's perspective; can they log in, complete a transaction, see their data?​ The Real Problem Isn't Maintenance. It's Misplaced Focus. Maintaining traditional UI tests often feels endless. Hard-coded selectors break with every UI tweak, which happens nearly every sprint. A clean, well-structure…  ( 11 min )

In professional software development, permanent data deletion is often a non-starter. Auditing, compliance, and recovery mandates require that we soft-delete records, marking them as inactive rather than physically removing them. The implementation, however, is a common source of bugs and security vulnerabilities. A manual approach requiring developers to remember a Where(x => x.RemovedAt == null) clause on every query is simply untenable. A production-grade soft-delete system must satisfy two non-negotiable requirements automatically: Read Consistency: Soft-deleted records must be filtered from every SELECT query in the application. Association Filtering: The filter must propagate when querying entity associations. Loading a Post must automatically exclude any soft-deleted Comments from…  ( 7 min )

Understanding DevOps — The Big Picture Software development involves many roles — developers, testers, and operations engineers — all working together to build and maintain applications. But how do these roles connect, and what exactly does DevOps do? This guide breaks it down simply, so even if you’re new to tech, you’ll understand how DevOps fits into the bigger picture. Imagine a big app like Instagram or Facebook. It takes multiple teams to make it work smoothly: Developers write and improve the code. Testers make sure everything works properly. Operations (Ops) run the app on servers and make sure it’s always available. Each team plays a vital role — and all of them must coordinate to ensure users get a seamless experience. Developers write the code that brings an app to life…  ( 8 min )

Recently, Mandiant published an in-depth look at PAM. We applaud Mandiant and Google as they continue to push toward a safer world, and their PAM guidance is packed with grounded, hard-won advice. It is also good to see non-human identities included in the scope. Service accounts APIs, workloads, and automation have real entitlements. Leaving NHIs out of PAM creates blind spots that attackers exploit and auditors eventually find. We also appreciate their PAM levels of maturity guidance. Teams can use their four levels, uninitiated, ad-hoc, repeatable, and iterative optimization, to help organizations of any size find the next steps in the right direction. This approach aligns with what we have seen in our Secrets Management Maturity research. GitGuardian is happy to help teams as they alig…  ( 10 min )

📘 Introduction: If you want to see where it all started, check out my first post about the 80 Days of Challenges here. 🛠 My Approach: 💻 Examples from the challenges For example, I built a Turn-Based FizzBuzz Game where the player competes against the machine. That one helped me practice while loops, string comparisons, and alternating turns, and made me appreciate how logic can make even simple games feel interactive. Another day, I created a Coin Flip Guessing Game to practice random.choice(), user input, and conditional logic, which made randomness and interactivity click for me. When I solved the 0/1 Knapsack Problem, I got my first real taste of dynamic programming and optimization logic, it was one of those “oh, so that’s how algorithmic thinking actually works” moments.

If you’ve been around crypto or blockchain long enough, you’ve heard it a thousand times... “Not your keys, not your coins.” But beyond being a catchy phrase, this statement gets to the very core of what blockchain stands for: trustless ownership. Let’s unpack what this means in practice, especially for developers and builders who design systems where “ownership” is baked into the code. At the heart of every crypto wallet lies one question: who controls the private key? 🔒 Custodial Wallets But here’s the catch: the convenience comes at a cost. You’re essentially trusting a third party to safeguard your funds, follow regulations, and not lock or freeze your account. You gain ease of use, but you lose absolute control. It’s similar to using a traditional bank: you own the balance, but the i…  ( 9 min )

The other day, a friend of mine was complaining that every month, their AWS bill is landing like a small novel: hundreds of line items, multiple accounts, and no clear picture of why costs changed. So, I started thinking, what it takes to build a modular AWS Cost Audit script to collect and summarize cost and usage data automatically. That experiment grew into a reusable FinOps toolkit for cloud teams, which is lightweight, transparent, and CI/CD-friendly. AWS gives incredible flexibility — but that also makes it easy to overspend. Idle EC2 instances, forgotten EBS volumes, over-provisioned RDS databases, and cross-region data transfers quietly add up. Even with native tools like Cost Explorer and AWS Budgets, many teams struggle to: Continuously monitor all resources across accounts Corr…  ( 9 min )

En ingeniería de software, todo programa funciona… hasta que deja de hacerlo. Y cuando lo hace, rara vez avisa. El testing no existe para demostrar que algo “anda bien”, sino para entender bajo qué condiciones deja de hacerlo. Es una práctica que revela lo que el entusiasmo del desarrollo suele ocultar: las grietas invisibles en nuestras suposiciones. Corregir un bug nunca cuesta lo mismo.

Rewriting software is a topic that sparks endless debates among engineers. The first reaction when joining an existing project is often: “This is a mess, let’s start fresh”. It’s tempting to imagine a perfect, clean system - elegant architecture, fewer compromises, faster development. Sometimes a rewrite is justified. But what’s often overlooked are the small fixes, edge case patches, and tweaks accumulated over time. That “messy” system is often stable because of these hard-earned adjustments. A rewrite might feel faster initially, but regaining that stability - rediscovering subtle fixes, handling edge cases, and testing thoroughly - often takes longer than improving the existing code. The key is balance. Rewrites aren’t inherently bad, but they come with hidden costs. Stability, accumulated fixes, and historical knowledge are valuable, and any rewrite should account for them before lighting the match. Don’t chase perfection blindly - sometimes improving what works is smarter than starting over. Happy coding!  ( 6 min )

Introduction and the Business Importance of Modern API Architectures APIs as a Strategic Asset Think about how organizations like Twilio and Stripe created billion-dollar enterprises by providing user-friendly APIs. Internal platforms are subject to the same idea. Development cycles are significantly shortened and teams become more independent when a company's internal systems offer dependable, consistent APIs. Why Architecture Matters Choosing the right architecture whether REST, GraphQL, gRPC, or asynchronous messaging depends on a company’s business goals, team skills, and the types of clients consuming the API. At Nile Bits, we help organizations evaluate and design architectures that align with both technical and business priorities. Our software development services and DevOps expert…  ( 18 min )

This article builds on our previous post, where we explored the high-level architecture of token exchange, identity federation, and how to run MCP servers in a secure and IdP-agnostic way. Now we shift into the hands-on phase: how to use ToolHive to enable an MCP server to query Google BigQuery for users authenticated via Okta. While we use Okta and Google Cloud as the example stack, this flow is adaptable to any IdP and any cloud provider with a compatible STS / federation service. You run an MCP server that receives requests from users who are authenticated via Okta. The MCP server must execute queries in Google Cloud BigQuery. You don’t want to manage Google service-account keys, embed JSON credentials in config, or lose per-user audit. You want: user-level attribution, least-privilege …  ( 10 min )

📘 Introduction In databases, indexing and hashing are techniques used to improve the speed of data retrieval operations. Without indexes, the database must scan every row to find a match, which is slow for large tables. B-Tree Index: Used for range and equality queries (e.g., searching roll numbers or CGPAs). B+ Tree Index: A variation of B-Tree that stores data only in leaf nodes, providing faster sequential access. Hash Index: Used for exact match lookups (e.g., searching by department name). Query Optimization ensures that the database uses the most efficient way to execute SQL queries — often by choosing the right index. Step 1: Create Table Step 2: Insert 20 Sample Records Step 3: Create B-Tree Index on Step 4: Fetch details of student with roll_no = 110 ✅ The EXPLAIN keyword shows how the query uses the index Step 5: Create B+ Tree Index on cgpa In MySQL, normal indexes use B+ Tree structure internally. CREATE INDEX idx_cgpa ON Students(cgpa); Then query: EXPLAIN SELECT * FROM Students WHERE cgpa > 8.0; Step 6: Create Hash Index on dept ⚠️ Note: MySQL supports Hash Index only on MEMORY (HEAP) tables, or in PostgreSQL using USING HASH. ✅ For MySQL: ✅ For PostgreSQL: Step 7: Retrieve students from ‘CSBS’ department Explain indexing, hashing, and optimization (use the intro above). 🧱 Table Creation and Data Insertion (Include screenshot of all students.) 🌳 B-Tree Index on Roll Number (Include query + EXPLAIN screenshot.) 🌲 B+ Tree Index on CGPA (Show query + EXPLAIN output for cgpa > 8.0.) 🧩 Hash Index on Department (Show query + EXPLAIN output for ‘CSBS’ department.) ⚙️ Query Optimization Mention how indexes reduce the time for searching records. 🏁 Conclusion Indexes and hashing make data retrieval much faster and efficient by avoiding full table scans.  ( 7 min )

A few months ago, I asked a colleague — “Can you pull all customer orders over ₹100 000 from the last year, group them by region and send me the top five?” In a traditional world, that request would mean a hand-written SQL query, back-and-forth with data engineering, debugging joins and checking column names. But thanks to Generative AI tools, I typed that same sentence into a chat interface — and within seconds got a working SQL query and result set. The shift isn’t just neat—it’s game-changing. Today, organizations are using AI to translate natural language into SQL, automate complex queries and open data access to wider teams.

💬 Introduction In Angular, displaying validation errors in a form can quickly become repetitive and verbose. It is to simplify this part that I have developed a small library: ng-input-validation, which centralizes and automates the display of error messages in an elegant and reusable way. In this post, I show you how I used to do it and how I do it today 👇 Before, for each form field, it was necessary to write several conditions to display the error messages: 👉 Result: a lot of repetitive code to maintain, especially when you have multiple fields. ng-input-validation With ng-input-validation, everything is managed automatically from the FormControl. And your FormGroup : Where before it was necessary to write several @if, today a single line is enough. The component automatically displays the correct error message according to the type of validation (required, email, minLength, etc.). You can also manage backend errors or add custom messages for each type of error. npm i ng-input-validation And don’t forget to import it into the Angular component. This library allowed me to: Save time on form management; Keep a cleaner and maintainable code; Standardize error messages in all my Angular applications. 👉 The project is open-source on npm: https://www.npmjs.com/package/ng-input-validation  ( 6 min )

Introduction AWS S3 Vectors promises "billions of vectors with sub-second queries" and up to 90% cost savings over traditional vector databases. These claims sound good on paper, but implementation details matter. How does performance actually scale? What's the accuracy trade-off? Are there operational gotchas? This post presents empirical benchmarks testing S3 Vectors from 10,000 to 10 million vectors, comparing performance and accuracy against FAISS and NMSLib.

Frontend development is evolving faster than ever. If you’re building apps, dashboards, or SaaS platforms, choosing between React, Next.js, and Vue isn’t just about syntax. It’s about scalability, performance, and ecosystem support. So, which one actually wins in 2025? Let’s break it down. React in 2025: Still the Powerhouse React remains the foundation for modern frontend development with 80% of enterprise teams still using it directly or via Next.js. Why it still dominates: Massive community and library ecosystem Seamless TypeScript support Continues to evolve with React Server Components Excellent for building shared design systems But watch out for: Requires extra setup for routing, SSR, and SEO Can feel “barebones” without additional libraries Steeper learning curve for stat…  ( 7 min )

Introduction When we talk about reference counting, everyone remembers one pain point: cyclic references. a.link = b b.link = a del a del b # ...but the memory is still allocated Interpreters like CPython solve this with an additional “cycle collector” (cycle GC), but this is a different system, with graph traversal, unpredictable pauses, and additional overhead. The idea is simple: refcount of those it pointed to. The problem with classic reference counting is that the model assumes the following structure: class Object: def __init__(self, name): self.refcount = 1 self.ref = None self.name = name def link(self, ref): if self.ref != ref: self.ref = ref ref.refcount += 1 def rc_dec(self): self.refcount -= 1 …  ( 9 min )

Sean and Amanda are back, moving along in their yearlong countdown of the 21st century’s greatest films, landing at the mind-bending David Lynch classic Mulholland Drive. They gush over Naomi Watts’s breakthrough turn, dissect every conspiracy-fueled interpretation and marvel at how Lynch mash-ups Americana, dashes of European surrealism, old-Hollywood glam and off-kilter outsider art into one unforgettable trip.

Three weeks ago, on October 15th, I hit publish on Liquidcode v2. After months of pivoting (read about that journey), I finally had something I believed in. A platform where frontend developers compete 1v1, the community votes, and your rank actually means something. I announced it on Dev.to and then... I waited. You know that feeling when you ship something? Equal parts pride and panic? Pride because holy shit, I actually finished something. As developers, we start a million projects. We finish maybe three. This was one of the three. Panic because what if it's trash? What if nobody cares? What if I spent months building something the world doesn't want? The first two days were brutal.

Why AI evaluation matters (and “vibes-based” QA fails) If you’re shipping LLM features, you’ve likely seen this: One prompt tweak fixes a niche case and silently breaks others. PMs ask, “Is this grounded?”, “Is it safe?”, “Why did JSON fail again?” Manual review is fine for demos, but it collapses at scale. AI evaluation turns fuzzy expectations into repeatable tests: Groundedness / context adherence: outputs should stick to provided sources. Structure validations: JSON schema and function calling stay correct. Safety & guardrails: content moderation, refusal checks, prompt-injection detection. Behavior & tone: measure helpfulness, politeness, and resolution quality. This tutorial uses the Future-AGI SDK to get you from zero to defensible, automated AI evaluation fast.

Because sometimes, the real challenge isn’t writing the code, it’s finding the perfect balance between portability and productivity. As a software engineer, I split my workflow across two worlds: MacBook Pro → my portable dev machine, where all my codebases live.

It was never there. And if it had been, I’d have dissolved it on day one. I run what some would call a software company. On paper, it's a complete organization with: a developer, an architect, a product owner, a DevOps engineer, and even a quality manager. In practice, all of that is me. And I have a dog who barks at every deployment — probably my only truly engaged stakeholder. Everyone says you need an agile team to build anything serious — a Scrum Master, a Product Owner, a few meetings to prove you exist. I considered playing all those roles myself — Scrum Master on Mondays, PO on Tuesdays, Agile Coach on Wednesdays… Then I realized: none of these roles ship code. So I never hired them. And since then… everything just works. No meetings. No ceremonies. Just code, decisions, and a bi…  ( 11 min )

💬 Introduction En Angular, afficher les erreurs de validation dans un formulaire peut vite devenir répétitif et verbeux. C’est pour simplifier cette partie que j’ai développé une petite librairie : ng-input-validation, qui centralise et automatise l’affichage des messages d’erreur de manière élégante et réutilisable. Dans ce post, je te montre comment je faisais avant et comment je le fais aujourd’hui 👇 Avant, pour chaque champ de formulaire, il fallait écrire plusieurs conditions pour afficher les messages d’erreur : 👉 Résultat : beaucoup de code répétitif à maintenir, surtout quand on a plusieurs champs. ng-input-validation Avec ng-input-validation, tout est géré automatiquement à partir du FormControl. Et ton FormGroup : Là où avant il fallait écrire plusieurs @if, aujourd’hui une seule ligne suffit. Le composant affiche automatiquement le bon message d’erreur selon le type de validation (required, email, minLength, etc.). Tu peux aussi gérer les erreurs backend ou ajouter des messages personnalisés pour chaque type d’erreur. npm i ng-input-validation Et n’oublie pas de l’importer dans composant Angular. Cette librairie m’a permis de : Gagner du temps sur la gestion des formulaires ; Garder un code plus propre et maintenable ; Uniformiser les messages d’erreur dans toutes mes applications Angular. 👉 Le projet est open-source sur npm : https://www.npmjs.com/package/ng-input-validation  ( 6 min )

I am studying for my AWS certifications. Everyone said: "Learn networking first." So I dove into the OSI model. The concept clicked when I stopped trying to memorize layers and started understanding what problem each layer solves. The OSI model is not something you memorize. It provides a framework for understanding how data moves from your laptop to AWS servers and back. Here is what I wish someone told me on day one. Before we dive in, let me explain why networking is not just theory. You cannot configure AWS VPCs without understanding Layer 3 (IP addresses). You cannot write Security Group rules without understanding Layer 4 (ports). You cannot troubleshoot connectivity without understanding all 7 layers.

Fun fact, I thought I had already written this post, but when I wanted to reference it, I found out that I didn't. In this post, I'd like to describe my approach when choosing a dependency. I'll first define what I mean by dependency in the context of this post. Then, I'll list a grid of several criteria to analyze possible dependencies with. A dependency is literally something your software depends on: infrastructure such as a filesystem or a database, network, etc. In the context of this post, however, I'd like to narrow the scope to a software dependency that you need to compile/run, i.e., a library. Different software stacks have different names for this library: Ruby calls it a gem Rust calls it a crate Python and Node.js call it a package Go calls it a module Maven/Gradle call it…  ( 11 min )

While testing my NativePHP Android application, I noticed that the back button / action wasn't behaving the way I would expect for a regular "native" application. I realised that it was behaving like a browser with it's history stack. If I navigated into sub-menus using the UI then started using the back button / action it would just take me back through my history instead of up the menu tree like a regular app would, so I thought I'd look into how to fix that behaviour. After a quick Google search, the answer ended up being a simple, single line change. By adding the following to your MainActivity.kt file, we can instead emit an event in JavaScript which can then be reacted to. webView.evaluateJavascript("window.dispatchEvent(new Event(\'native:backpressed\'))", null) Caution: If you ta…  ( 7 min )

TL;DR Letting an LLM write runtime code feels powerful until you run it every weekday at 9:00. Small per-step errors compound across long workflows. We shifted code generation out of runtime and into the planning phase using a typed DSL, validated components, and MCP. The LLM plans and composes; a deterministic engine executes. Result: lower failure rates, bounded costs, and behavior teams can trust. We started the common way: the model wrote code on the fly to call tools. After months of tuning, reality intruded: 20%+ end-to-end failure rate Missing await Type mismatches Edge cases that crashed workflows The math hurts: if each step is 95% accurate, a 10-step job succeeds about 0.95^10 ≈ 59.87%. That is not usable for customer-facing operations. We moved generation from runtime to the …  ( 8 min )

Let’s be honest: onboarding new clients manually sucks. A few months ago, at Gonzo Digital Marketing Australia, I decided to fix this the developer way — through automation. Here’s what I did 👇 🧩 Step 1: Defined the Workflow Every client went through the same 5 steps — proposal → approval → payment → kickoff → reporting. ⚙️ Step 2: Integrated Everything When a client signs a proposal → they automatically receive a welcome email When payment is confirmed → our internal Slack gets a “New Project Live” message When onboarding is complete → GDrive folder & reports are auto-created No code. No hassle. Just time saved. 💡 Step 3: Why This Matters This small automation turned into a major productivity boost — cutting admin time by 70% and improving client satisfaction.

In the previous part of this series, we introduced the concept of message history and explored how agents in Pydantic AI can maintain conversational context across multiple interactions. In this part, we temporarily set aside message history and focus instead on a new concept in Pydantic AI: the Multi-Agent Pattern. This pattern allows us to design modular, cooperative AI systems that distribute responsibilities and work between agents to complete a task. The Multi-Agent Pattern is a design principle in which several agents cooperate to complete complex tasks. Each agent is responsible for a specific domain or capability, and together they form a distributed intelligence system.

Introduction As modern enterprises grow, so does the demand for real-time, high-quality voice communication. In this post, we’ll explore five proven strategies developers use to scale FreeSWITCH systems for performance, stability, and future growth. Instead of depending on a single large server, distribute your FreeSWITCH instances across multiple nodes. Tip: Implement health checks so the load balancer can dynamically reroute SIP traffic if a node goes down. Running FreeSWITCH on Docker or Kubernetes enables predictable scaling, simpler management, and faster deployment cycles. Kubernetes’ auto-scaling and self-healing capabilities are particularly effective for VoIP workloads. Media processing (RTP) is one of the most resource-intensive aspects of FreeSWITCH. Consider deploying dedicated media relays for handling conference calls and IVRs. As you scale horizontally, managing configs across multiple FreeSWITCH nodes becomes complex. Scalability isn’t just about adding servers — it’s about understanding performance trends. 🔍 Test call concurrency and media performance before production deployment. Scaling FreeSWITCH isn’t a one-time setup — it’s a continuous optimization process involving load balancing, automation, monitoring, and modularization. building a call center platform or a global communication solution, following these principles ensures your VoIP system remains stable, efficient, and ready for growth.  ( 7 min )

This is a first-person, hands-on writeup of how I experienced using Copilot coding agents today. I include examples, a gotcha I hit while using it, and a short checklist so you can try it in your repos. I started experimenting with Copilot coding agents because I wanted to scaffold a lot of things which IDE-based agents do not, and to see what an assistant could do for me (refactoring scaffolding, creating test harnesses, running quick migrations) and actually execute code in a prepared environment instead of just suggesting edits.

Upon investigation, it was discovered that the website had been built using Elementor and several Elementor-related add-ons installed in 2023. Meanwhile, the website had automatic updates enabled, which caused Elementor to update to the latest version while the outdated add-ons remained incompatible. This conflict led to the website’s functionality breaking entirely. According to Asaaju Peter, this situation is common among WordPress users who rely heavily on multiple third-party add-ons and do not perform version compatibility checks before updating. He emphasized that maintaining a WordPress website is not just about installation but also about ensuring stability, performance, and cautious management of plugin updates. He advised users to avoid unnecessary add-ons and disable auto-updates unless compatibility is confirmed. Phemight Technologies continues to offer website maintenance, troubleshooting, and optimization services to help businesses maintain reliable and secure online platforms.  ( 6 min )

Introduction: The Battle Against Credit Card Fraud Imagine this scenario: You're having a normal day when suddenly your phone buzzes. It's your bank asking if you just made a $1,500 purchase in another country. Your heart sinks. You check your wallet—your credit card is still there. Someone has stolen your card information and is trying to spend your money. This happens to millions every year, but thanks to modern credit card fraud detection systems, most attempts are stopped before any money is lost. Credit card fraud detection has evolved from manual reviews to advanced artificial intelligence systems that spot suspicious activity in milliseconds. In this guide, we'll explore how these systems work, why they're essential, and how companies like Labellerr AI are helping create smarter, …  ( 9 min )

Why Use rem Instead of px for Padding? /* Before */ padding: 24px 74px; /* After */ padding: 1.5rem 4.625rem; But this is one of those small shifts that has a big impact in modern CSS, especially when building scalable and accessible interfaces. rem Responds to User Accessibility Settings The rem unit is relative to the root font size (typically the browser default of 16px). px values do not scale → the layout becomes cramped and harder to read. rem values do scale → spacing and layout grow proportionally. This means a UI built with rem is more accessible and readable for all users. em? em values are relative to the element’s own font-size, which can lead to padding and spacing changing unexpectedly when typography changes. rem keeps spacing consistent, even if a component’s font size is adjusted. Feature rem (Recommended) em Relative to root font-size (html) ✅ Yes ❌ No Padding stays consistent when element font-size changes ✅ Yes ❌ No Ideal for layout spacing (padding, margin, gap) ✅ Yes ❌ No Works well in design systems & token scales ✅ Yes ❌ No Best for sizing elements relative to their own text ❌ No ✅ Yes Common use Global spacing & layout Inline elements that scale with text Switching from px to rem makes your UI: More readable More accessible More visually consistent Easier to maintain Better prepared for responsive layouts If you're building a modern design system or want your UI to scale gracefully across devices and accessibility settings, use rem for padding and layout spacing.  ( 6 min )

The core value of AI search tools is that they are fundamentally changing how we interact with information. Traditional search engines provide an "index," requiring users to click links, read, filter, and synthesize answers for themselves. AI search, however, attempts to bypass these intermediate steps by directly understanding complex user intent, integrating web information, and generating a relatively complete, ready-to-use "answer." This "answer-driven" experience is iterating rapidly, and many excellent products with different approaches have emerged. Each has its own focus and is suited for different needs. Perplexity AI: The Rigorous Answer Engine Perplexity AI is perhaps the product that best represents the "answer engine" model today. Its interface is extremely minimalist, center…  ( 9 min )

For as long as we’ve been building with machines, we’ve followed one core rule: faster is better. Lower latency, higher throughput, less waiting; that was gospel. Nobody wanted to wait 600ms for a button to respond or watch a spinner that lasts longer than their attention span. If it was slow, it was broken. Case closed. So naturally, when AI tools started creeping into our dev workflows, autocomplete, agents, copilots, you name it, the same principle applied. Make it fast. Make it feel instant. Make it look like magic. But here’s the thing: AI isn’t magic. It’s inference. It’s pipelines and RAG and context and tool calls. It’s juggling messy context and probabilistic guesses. And if you want something smarter than glorified autocomplete, you need to build a pipeline of processes to provid…  ( 15 min )

The Value-Centric Philosophy of Rust Ever typed let a = 8; let a = 9; in Rust and wondered why it didn’t feel like “reassignment”? That moment reveals a core philosophy: **values are central, and variables are mere handles.** 1. Why Rust Feels Different Most programming languages—C, Java, Python—treat variables as containers. They store values, which you can freely replace: int a = 8; a = 9; // Replace content; 'a' persists Rust flips this view: Values exist independently. Variables are handles, not storage boxes. Operations are about who can access the value, not changing the variable itself. Key takeaway: Values are central; variables are temporary handles. 2. Values at the Center let a = 8; let a = 9; // Shadowing: new 'a' handles 9; old value 8 persists until scope ends Va…  ( 7 min )

Most IT leaders already understand that AI can make operations smarter. The challenge isn't the technology — it's the conversation. Convincing leadership to fund AI-driven IT means moving past buzzwords and showing clear, measurable business outcomes. 1 Shift the Conversation: From Cost to Capability Executives don't invest in savings — they invest in capability. AI-driven IT is not an add-on. It's a force multiplier that transforms what your IT function can deliver: Predictive resolution instead of reactive firefighting Enterprises using predictive AI in ITSM report 45% faster resolution times and 50% fewer escalations. Every hour saved in downtime protects both productivity and revenue flow. When you stop framing AI as a tool and start presenting it as a capability, leadership sees it fo…  ( 9 min )

Executive Summary AI email assistants are increasingly vulnerable to prompt injection—a subtle but potent attack vector where adversaries embed hidden instructions inside routine-looking emails. These manipulations bypass traditional security controls, leaving no trace in system logs. The result: unauthorized actions, silent data exfiltration, and compromised operational integrity. This whitepaper outlines a forensic-first defense framework, emphasizing timestamped logging, input isolation, and post-incident reconstruction. It closes with a tactical self-assessment checklist to evaluate system exposure. Prompt injection is the act of embedding adversarial instructions into content that an AI assistant will read and interpret. In the context of email, this often takes the form of: Hidden …  ( 9 min )

TL;DR The EU’s new Cyber Resilience Act (CRA) will change how WordPress agencies, plugin developers, and care-plan providers handle security, compliance, and updates. Here’s what it means for you, and what you need to do before 2027. You don’t need to know the full text of the EU’s Cyber Resilience Act to feel its presence. If you build or maintain WordPress software (with a commercial intent) and it’s used in the EU, this law most likely applies to you. The CRA expects you to know what dependencies your code includes. You’re expected to have a process in place when someone reports a vulnerability. You’re expected to separate security updates from everything else. And yes, if something gets exploited, you have a deadline for reporting it, just like every other digital product vendor in …  ( 13 min )

Over the past few weeks, I’ve been exploring a range of AI tools, testing them in real projects and integrating them into my daily workflow. My goal was simple: to see how far AI can truly go in helping developers build real, production-ready products. During this time, I used several of these tools to ship client projects, including a full web MVP built in just 30 days and an Android mobile app. Since I already had the UI designs, my main focus was turning them into fast, pixel-perfect frontends and integrating a solid backend behind them. Throughout that process, I tried dozens of AI tools for both frontend and backend tasks. In a space where every major company is experimenting with AI, I wanted to dig deeper and test tools that don’t just generate code but also understand design. In th…  ( 25 min )

Hello Dev.to! I'm excited to announce the Alpha release of Selur, a project that fundamentally re-examines the relationship between HTML, CSS, and JavaScript. Selur is a Pure CSS UI Declaration Engine. It doesn't only give you components; but also the missing architectural layer that puts visual logic and stateful UI behavior back into CSS, where it always belonged. The original web contract was simple: But today, we often see JavaScript handling presentation (UI frameworks rendering DOM elements), CSS getting polluted with utility classes that mimic structural concerns, and HTML becoming generic, non-semantic containers. Selur re-establishes this contract by moving all UI interactivity and visual state management back to pure CSS, where it truly belongs. Selur isn't a component library; i…  ( 8 min )

Introduction Modern data engineering projects typically use Python for orchestration (Airflow DAGs), data transformation, and DBT or SQL for data ingestion. At scale, however, deployment becomes a significant bottleneck. My data engineering team manages ingestion for a data warehouse containing nearly 10,000 tables. We follow a standardized approach where each table requires at least 5 programs covering the standard pipeline: file ingestion → staging → transformation → ODS layer. This results in over 50,000 program files requiring deployment. Our Azure DevOps CI/CD pipeline was taking nearly 30 minutes per deployment — unacceptable for any development workflow. Having previously managed deployment pipelines for Java microservices with comprehensive test suites, this was excessive for our…  ( 9 min )

When your SQL queries start slowing down, one of the first solutions that comes to mind is adding an index. But while indexes can dramatically speed up data scans and searches, they can also slow down data mutations like INSERT, UPDATE, and DELETE. In this article, we’ll break down how indexes work, why they matter, and when you should (or shouldn’t) use them — all with practical SQL examples. An index in a database is similar to an index in a book — it helps you find specific information faster. Instead of scanning the entire table row by row, the database engine uses the index to jump directly to the relevant data. Indexes are typically implemented using B-trees, which allow the database to quickly scan and retrieve the desired rows with logarithmic complexity instead of linear. When y…  ( 7 min )

Most backend frameworks today are built on foundations from a different era. Express sits on Node.js HTTP. NestJS sits on Express. Each layer adds abstraction, dependencies, and constraints. What if we started fresh? YasuiJS is a new TypeScript framework for building REST APIs, built on Web Standards from day one. No Express underneath. No Node.js HTTP layer. Just the Fetch API, Web Standards Request/Response, and a lightweight server adapter (srvx) that works across runtimes. The result? A framework that runs anywhere—Node.js, Deno, Bun, Cloudflare Workers, Vercel Edge—with the elegant decorator-driven DX you'd expect from modern frameworks, but without the bloat.

When building a rendering workstation, many artists and designers assume that adding more GPUs will automatically multiply rendering performance. While this is true for many offline render engines like Redshift, Octane or Blender Cycles, not all 3D software can take advantage of multiple GPUs. In fact, some popular real-time rendering tools are still limited to a single GPU, which often surprises users who have invested heavily in multi-GPU setups. In this article, we will look at several widely used 3D visualization tools that only render on one GPU, explore why a single GPU is enough or sometimes necessary for their workflows and find the suitable software for your projects. For offline render engines such as V-Ray, Redshift, or Octane, multi-GPU rendering is a game changer. By distribu…  ( 10 min )

If you’ve been learning Python for a while, you’re probably familiar with for and while loops. They’re the backbone of iteration — letting you repeat actions efficiently. But here’s a twist that often surprises beginners: Python allows you to use an else block with loops. Wait… an else block? With loops? That’s right! In Python, the else clause isn’t just for if statements — it can also appear after a for or while loop. And when used correctly, it can make your code cleaner, more expressive, and even more Pythonic. Let’s dive deep into how it works, when to use it, and how to avoid common pitfalls. 🧩 What Is the else Block in Loops? In Python, both for and while loops can have an optional else clause. The basic syntax looks like this: for item in iterable: or for a while loop: while condi…  ( 10 min )

I picked up Go recently while building the backend of a crypto tracker. This tracker allows users to manage their cryptocurrency holdings and calculate their wallet value in real-time. One of my favorite learnings so far is value receivers and pointer receivers, and how everything works under the hood. Go passes arguments by value, not by reference. This means it creates a copy of the argument and passes that copy to the function. Understanding this is crucial to writing efficient Go code. When you use a value receiver, Go creates a copy of the struct. Any modifications you make inside the function only affect the copy, not the original. type Wallet struct { User string TotalValue float64 } // Value receiver - receives a copy func (w Wallet) UpdateValue(newValue float64) { …  ( 9 min )

MVC (Model–View–Controller) — detailed, plain English What it is: Parts & role Model — holds the data and the business rules. Think: database records, validation logic, and how data is transformed. It’s the source of truth. View — the user-facing presentation layer. HTML, mobile screens, or UI components that display Model data. Controller — the mediator that receives user input (clicks, form submits), talks to the Model to read/update data, and picks which View to render. Typical request flow (web example): User clicks a button in the View. Controller receives the request/route and validates input. Controller asks the Model to fetch/update data. Model returns data (or an error). Controller chooses a View and passes the Model data to it. View renders the final UI the user sees Benefits C…  ( 8 min )
